Professional career
Baltimore Ravens
Osemele was selected in the second round in the 2012 NFL Draft by the Baltimore Ravens. He started at right tackle in every Ravens game during his rookie season. He replaced the injured Jah Reid at left guard for the Ravens' playoff run. This, along with the insertion of Bryant McKinnie at left tackle and the move of Michael Oher to right tackle, solidified the offensive line. With the Ravens finishing 10-6, the team won the AFC North pennant and eventually won Super Bowl XLVII over the San Francisco 49ers, making Osemele's rookie year successful giving him his first championship title. On November 1, 2013, it was announced Osemele would have back surgery. After playing seven games, he would finish the rest of the 2013 season on injured reserve. Osemele successfully recovered from back surgery and started all but two games for the Ravens in the 2014 season.
Osemele signed a five-year, $60 million contract with the Oakland Raiders on March 10, 2016. He was selected to his first Pro Bowl for the 2016 season along with fellow Raider offensive linemenDonald Penn and Rodney Hudson. He was also named First-team All-Pro. He was also ranked 95th on the NFL Top 100 Players of 2017. On December 19, 2017, Osemele was named to his second Pro Bowl along with fellow Raider offensive linemen Donald Penn and Rodney Hudson for the second straight year. As of October 2018, he was the second-highest paid left guard in the NFL in average salary at $11.7 million, behind the Jaguars' Andrew Norwell and ahead of the Tampa Bay Buccaneers' Ali Marpet.
On March 10, 2019, the Raiders agreed to trade Osemele and a 2019 sixth round draft pick to the New York Jets in exchange for a fifth round pick. The deal was completed on March 14, 2019. On October 15, 2019, it was revealed that Osemele suffered a shoulder injury and was contemplating surgery. Osemele’s doctors told him that he needed surgery for his injury, but the Jets organization was not approving his surgery, so he was fined for every practice that he missed due to his injury. On October 26, 2019, Osemele was released from the team after undergoing shoulder surgery.
