Cleveland Browns starting right tackle Jack Conklin suffered a season-ending left knee injury Sunday, coach Kevin Stefanski confirmed Monday.

Stefanski didn’t provide specifics of the injury, but a source told ESPN’s Adam Schefter that tests revealed that Conklin tore the ACL and MCL in his left knee. Conklin will undergo season-ending surgery.

Conklin was carted off the field with his knee injury Sunday in Cleveland’s 24-3 victory over the Cincinnati Bengals.

Conklin injured his left knee while pass protecting in the first half against the Bengals. Defensive end Trey Hendrickson rolled into Conklin’s knee while rushing from the other side of the Browns’ pocket.

Conklin was an All-Pro his first year in Cleveland in 2020 but has battled injuries since, including a torn patella in his right knee in 2021.

Rookie Dawand Jones, a fourth-round pick out of Ohio State, replaced Conklin in Sunday’s game.
