McCorkle fought out of C-4 MMA. He fought at Super Heavyweight for most of his career, weighing as much as 320 lbs. McCorkle has several nicknames, but "Big Sexy" is his best known moniker. MMA journalist Ariel Helwani coined his other main nickname "The Curtain Jerker" during a pre-fight interview. He was also known as "The Hater" early on in his career. After winning his first four fights, McCorkle faced Jeremy Norton on New Year's Eve 2006. During the bout, McCorkle dislocated his shoulder and broke his arm, but was able to continue and took a split decision victory. Due to the injury, he was out of action for fourteen months of physical therapy before he could return to MMA.
Legends of Fighting
McCorkle fought multiple times for an Indianapolis promotion called Legends of Fighting and remained undefeated with them, holding a 9-0 record and the promotion's Super Heavyweight Championship belt.
On October 7, 2006 McCorkle fought Robert Hogan at King Of The Cage: Meltdown, winning via TKO in the opening round.
Ultimate Fighting Championship
McCorkle signed a four-fight contract with the UFC in July 2010. After agreeing to sign with the UFC, his debut opponent was announced as the K-1 and Pride Fighting Championships veteran Mark Hunt at UFC 119 in McCorkle's hometown of Indianapolis. In order to make weight for the fight, McCorkle had to cut down to 265 lbs - a weight he had not hit since the age of 18. McCorkle won the fight in just 67 seconds, after locking in a straight armbar from his back. It was later revealed that McCorkle's armlock had caused significant damage to Hunt. Due to the onslaught of publicity he received for his win over Hunt, McCorkle's next fight was the Co-Main Event of UFC 124. He fought 6'11" Dutch fighter Stefan Struve in Montreal, Quebec. Struve and McCorkle traded trash talk on the Internet in the weeks leading up to the bout, which was a new experience for the usually reserved Struve. After McCorkle unleashed a continual barrage of taunts via his Twitter account, Struve issued a contest in which fans would Photoshop insulting pictures of McCorkle. The winner of the contest was promised the bloodstained fight gloves Struve was to use against McCorkle. The eventual winner of the contest submitted a picture of McCorkle as Justin Bieber, which led McCorkle to show up at the weigh-ins wearing a Bieber-style wig for photographers. When the fight began, McCorkle came out strong in the opening minutes, forcefully slamming Struve onto the ground and securing a kimura on him that nearly led to a tap out. After a struggle that sapped McCorkle of his energy, Struve was able to reverse the hold and pound him out, winning the fight by TKO. McCorkle next fought Christian Morecraft on March 26, 2011 at UFC Fight Night 24. After a closely contested first round, Morecraft came out and dominated the first four minutes of the second round. The referee briefly stopped the fight for two minutes after Morecraft delivered an illegal low blow to McCorkle's groin. When the action resumed, McCorkle dove in for a takedown but Morecraft was able to leverage this attempt into a standing guillotine choke that left McCorkle unconscious. In the spring of 2011, the UFC released McCorkle from his contract following back-to-back losses against Struve and Morecraft. On October 17, 2011, ESPN announced that Sean McCorkle would be a featured heavyweight in the video gameUFC Undisputed 3. The game was released for Xbox 360 and PlayStation 3 on February 14, 2012. The game went on to sell over one million copies.
After his release from the UFC, McCorkle won his next five fights with various promotions. He then signed to Bellator Fighting Championships, and on March 9, 2012 at Bellator 60 he made his debut in a catchweight fight against Richard White, winning via first round submission.
Rivalry with "The World's Strongest Man"
Immediately after his win at Bellator 60, McCorkle lost three straight fights for the first time in his career. He then signed with Polish promotion KSW to face the five time World's Strongest Man, Mariusz Pudzianowski. With McCorkle seeming to be at a low point in his career, many fight observers did not expect much from him in the bout. The two met at KSW 23 on June 8, 2013. When the fight began, Pudzianowski came out swinging and took it straight to McCorkle. The two struggled fiercely, with Pudzianowski controlling the tempo of the match until he stepped into a hard jab from McCorkle which subsequently dropped Pudzianowski. McCorkle was able to quickly capitalize and locked in a kimura, submitting Pudzianowski. The unexpected outcome of the fight made news immediately, and the notoriety of the bout led both men to agree to a rematch. McCorkle and Pudzianowski met again at KSW 24 on September 28, 2013. According to sports writer Chuck Mindenhall, "The two met like titanic slabs in the middle of the ring." Pudzianowski was able to quickly take the fight to the ground, where he remained on top as the two grappled for the entire first round. The scene repeated itself in the second round, but midway through McCorkle went for a kimura and was able to reverse Pudzianowski and end up on top. The fight was only scheduled for two rounds, and Pudzianowski took the decision victory. After the fight, McCorkle asked KSW for a third match with Pudzianowski, which was never granted.
Professional Wrestling
Sean McCorkle also made appearances for Freedom Pro Wrestling, a promotion based in Wisconsin. On April 20, 2012, McCorkle won his debut match against C.J. O'Doyle, the promotion's current heavyweight champion. McCorkle was called "a smack-talking jobber."
Retirement
On September 29, 2014, Sean McCorkle officially announced his retirement at the age of 38 during a light-hearted interview on The MMA Hour with Ariel Helwani. He also admitted he had been suffering from "miserable" back injuries for some time. McCorkle said he is currently focused on managing other fighters.
