PITTSBURGH (AP) — T.J. Watt returned a fumble 17 yards for the go-ahead touchdown midway through the fourth quarter as the Pittsburgh Steelers edged the Cleveland Browns 26-22. The game was overshadowed by a gruesome left knee injury to Browns running back Nick Chubb. The four-time Pro Bowler left on a cart after getting hit low by Pittsburgh safety Minkah Fitzpatrick. The Steelers improved to 1-1, beating Cleveland at home during the regular season for the 20th straight time. The Browns fell to 1-1 and likely will be without one of their best players for a while.
