In December 2016, at the 54th WBC Convention, president Mauricio Sulaiman announced that a rematch would take place between González and Cuadras for the WBC title in March 2017. The winner of the rematch will need to fight WBC #2 mandatory and WBC silver champion Srisaket Sor Rungvisai. González stated he hadn't agreed to a rematch or signed any contracts for a rematch to take place as he was not obligated to do so. González also spoke about the purse offered to him for a rematch, "The HBO people are offering me very low money, so I can not accept that fight. I've been struggling to get a good purse, because we are the world's number one pound for pound." It was reported that González was looking for a purse of around $1 million.On 5 January González's manager Carlos Blandon said that an opponent would be announced in ten days. A day later, due to González not being obliged to give Cuadras a rematch, Sulaimán stated that Sor Rungvisai will get a chance to fight González next. The fight was officially announced on 7 January and served as the co-feature for Gennady Golovkin vs. Daniel Jacobs at Madison Square Garden on 18 March 2017. Coming into the fight Rungvisai had only one loss since 2010, which came to Cuadras in 2014 via technical decision.

González vs. Sor Rungvisai II
K2 director Tom Loeffler stated on 31 March that González would seek a rematch with Sor Rungvisai. On 4 April 2017 the WBC ordered a direct rematch to take place between González and Sor Rungvisai. The winner of the first fight was due to fight mandatory challenger Carlos Cuadras. However, due to the direct rematch, the WBC ordered Cuadras to fight the next available contender, former unified flyweight champion Juan Francisco Estrada for the WBC interim title. The winner of both fights would then proceed to fight each other. WBC rationalized this with the following statement,Loeffler confirmed a date in the fall of 2017 would be considered and a venue will be discussed with representatives of Rungvisai. On 6 June Loeffler said the rematch would take place on 9 September on HBO at a location in California. It was said the Japanese super flyweight Naoya Inoue would be in line to make his American TV debut on the same card. On 7 June González travelled to Japan to negotiate a deal with Teiken Promotions for the fight. One of the main reasons for discussing the contract, was his purse. It was revealed by Mexican promoter Osvaldo Küchle, that Cuadras and Estrada would fight on the undercard for the WBC interim title. On 6 July Tom Loeffler announced the fight would take place at the StubHub Center in Carson, California. The event also features WBO champion Naoya Inoue and is considered historic as one of the biggest cards of all time in the smaller weight classes. It was confirmed the fight would be shown live on Sky Sports in the United Kingdom.
At the 7-day weigh in on 3 September González weighed 119.8 lbs and Rungvisai weighed in at 119 lbs. Per WBC rules, both boxers were required to weigh no more than 121 lbs. At the official weigh-in one day before the fight, González tipped the scales at 114.8 lbs, while Sor Rungvisai weighed 115 lbs. González would be paid a career high $600,000 purse, while Sor Rungvisai would make $170,000.
On fight night, in front of a pro-González sell-out crowd of 7,418, González suffered his second consecutive career defeat and failed to regain the WBC title, after being knocked out by Sor Rungvisai in the fourth round of their rematch. The opening round started with both fighters throwing heavy shots. Sor Rungvisai began to work the body straight away. In round 4, González was knocked down hard from a left to the head. González beat the count getting up at 7, but on unsteady legs. Rungvisai then finished the badly hurt González with a right to the head that put him down flat on his back. Referee Tom Taylor didn't bother with a count, waiving the fight off at 1:18 of the round. González was taken to the hospital after the fight for precaution. Like the first fight, an accidental headbutt occurred in round 1, when González complained and the crowd booed, the referee warned Rungvisai. The fight averaged an audience of 796,000 viewers on HBO and peaked at 835,000 viewers.
After the fight, Srisaket Sor Rungvisai stated that he had prepared for four months in order to knock González out, "I trained very hard for four months. I fought for Thailand, and this is what I dedicate this fight to, Thailand. For the first fight I only trained for two months. I knew I was going to knock him out." González was humble in defeat, "We were both trading punches, but his were harder, and they landed harder. I was very hurt the second time when I was knocked down, but I think I'll be OK." Promoter Tom Loeffler also spoke to HBO in regards to González's future, "I don't think he's done. When you fight a guy like Srisaket, he took the opportunity of winning the lottery. He beat the No. 1 pound-for-pound fighter and beat him in New York, and then he beat him more convincingly the second time. Now he has to be considered one of the best in the world. You saw Roman really packed the house, and Srisaket came into a hostile environment and proved he is a true champion. He has tremendous punching power." CompuBox stats showed that Rungvisai landed 80 of his 291 punches thrown and González landed 58 of 212. All 80 of Rungvisai's landed punches were power shots. González stated that he wouldn't return to the flyweight division, as he was unable to reach the 112 lbs limit and that he was interested in competing for a fifth world title, but he was also considering retirement.
Inactivity
Weeks after the fight, González stated that he was planning to continue his career. Teiken Promotions was said to be looking to arrange a fight against WBA champion Kal Yafai. Yafai replied to reports that González wanted to fight him by replying, "Happy days, I’ve wanted González for a long time," although he would have to get past his mandatory fight first. González spoke out regarding challenging Yafai after being ranked # 2 by the WBA, "It is a blessing to know that the WBA has placed me at number 2 in the rankings. I am grateful to Gilberto Mendoza for this opportunity." González didn't rule out fighting WBO champion Naoya Inoue, stating his next fight could be as soon as February. González wished to take up an interim fight, before challenging for a world title. He said, "I am never going to fight in bad condition. I take good care of myself, that's why I think I need a preparation fight." After being trained by Japanese coach Sendai Tanaka in his last fight, González made his intentions clear that he wanted to work with Félix Trinidad's father and ex trainer Don Felix. Fellow countryman and former two-weight world champion Rosendo Álvarez advised González to return to flyweight, stating it would be too much for him to remain at super flyweight and even more dangerous to move up to bantamweight. According to Tom Loeffler on 22 November it was believed that González would make his ring return around April or May 2018, possibly on the undercard of a Gennady Golvokin fight. Loeffler also stated that González would not be part of the planned SuperFly 2 card.On 11 January 2018 González hired Gustavo Herrera as his head trainer, from Managua, Nicaragua at the Roger Deshon gym and stated his intention to remain at super flyweight. On 8 April veteran Mexican boxer Pedro Guevara was being lined up to be González's next opponent, likely for Golovkin's undercard on 5 May 2018. Terms had been agreed for a 10-round super flyweight fight between both parties, however the fight had not been announced until the date and venue was confirmed. After Golovkin vs. Martirosyan was announced for 5 May at the StubHub Center in Carson, promoter Loeffler confirmed that González would appear on the undercard. On 24 April González released a statement saying he would not fight on 5 May after an opponent was not officially confirmed. He went on to state that he would likely return in June 2018 in Nicaragua, where he last fought in 2015. According to González's manager, Carlos Blandon, Gonzalez was unable to get a VISA. Three scheduled appointments in the space on 30 days had been cancelled. Blandon stated they were still waiting on the VISA issue as González wanted a camp outside of Nicaragua. He also stated González would likely return in September 2018. On 30 May 2018 it was reported the California State Athletic Commission required González to pass new neurological examinations before the ban would be lifted. González initially passed the exams after his knockout loss to Rungvisai in September 2017. The reason for the additional tests would be for precautionary measure.
González vs. Fuentes, Diocos
According to ElNuevoDiario on 13 July 2018 González was looking for an opponent for the undercard of the Canelo Álvarez vs. Gennady Golovkin rematch on 15 September at the T-Mobile Arena in Paradise, Nevada. At the time, the two likely opponents were Pedro Guevara and former world minimumweight champion Moisés Fuentes. On 20 August it was announced that González would fight Fuentes in a 10-round bout to open the PPV telecast. González returned to winning ways after he knocked out Fuentes in round 5. Fuentes was well beaten and bloody at the time referee Robert Byrd halted the fight, at 1 minute, 44 seconds. Fuentes lacked the power to hurt González whenever he did land. González dominated Fuentes with sustained combinations in the same way he had done prior to his two losses. Fuentes suffered a cut over his right eye in round 2, with the dripping blood giving him problems with his visibility. González did not target the eye, instead he mixed up his shots from body to head. There was little action in round 1, as both boxers fought cautiously. González earned $200,000, whilst Fuentes made $35,000 for the bout. CompuBox showed that González landed 145 of 390 punches thrown, while Fuentes landed only 47 of his 244 thrown.On 31 October it was reported that González would return to the ring on 8 December 2018 on the final televised boxing card on HBO. According to ESPN Deportes, the likely opponent was former world champion Pedro Guevara in a 10-round bout. A day later, the fight was announced to take place at the StubHub Center in Carson, California.
On 25 November Tom Loeffler told ESPN, González was unable to shake off a knee injury he suffered during his training camp and would no longer fight Guevara on the card. González would be out for up to six weeks following an arthroscopic surgery. Loeffler revealed Juan Francisco Estrada would likely replace González and fight Guevara on the same card.
In early December, González underwent successful surgery on his right knee.
González returned to the ring on 23 December 2019 on the undercard of the Ryōta Murata – Steven Butler fight in Yokohama, Japan. His opponent was Diomel Diocos. González wasted no time and quickly broke down the overmatched Diocos with powerful combinations, staggering him badly in the second round. Referee Yuji Fukuchi stopped the action and gave Diocos a standing eight count for him to collect himself. But as soon as the fight resumed, González continued to land punches on Diocos at free will, prompting the referee to step in and stop the fight thus giving González the victory via second-round stoppage.
González vs. Yafai
On 14 January 2020, Matchroom Boxing promoter Eddie Hearn announced González would challenge the WBA super-flyweight champion Kal Yafai on 29 February at the Ford Center at The Star in Frisco, Texas. The fight was on the undercard Mikey Garcia vs. Jessie Vargas welterweight main event.Despite having some success in the early rounds, Yafai was unable to fully capitalize on his bigger size and reach advantage, allowing González to get close and dictate the pace of the fight with his relentless pressure and brusing body shots. González' high work rate and body attacks began to take an early toll on the champion who became increasingly slower and fatigued, even losing his mouthpiece several times over the fight. In the seventh round González unloaded on a fatigued Yafai and a sweeping right hand knocked the champion off balance. Yafai finally fell to the canvas late in the eighth round from an accumulation of punches, but he got up to finish the final few seconds of the round on his feet. González quickly ended the fight in the ninth round after landing a huge overhand right that put Yafai on the floor for the second time. Referee Luis Pabon waved off the fight at the 0:29 mark, awarding González the WBA title via ninth-round TKO. At the time of the stoppage González was ahead on all three judges' scorecards with 80–71, 77–74 and 78–73. He was later promoted to WBA champion, and said he plans on fighting the other champions at super flyweight to unify the titles.
