"Barkley has also been named to the Madden 99 Club -- a first for an Eagles offensive player.
Starring on the cover of Madden NFL 26 and being named to the Madden NFL '99 Club' are both dreams come true," Barkley said. "I'm grateful to my teammates, coaches and Eagles fans for their support, and I can't wait to hit the field again to give Madden players more highlight-reel moments in Madden NFL 26."
Barkley, the reigning Associated Press Offensive Player of the Year, is coming off one of the best seasons for a running back in NFL history. He rushed for 2,504 yards over the regular season and the postseason, breaking the single-season record."
