One of the only negative developments for the Browns on Thursday night was the left knee injury that knocked defensive tackle Mason Graham out of the game.

Graham was injured in the first half of the 27-24 win over the Steelers and did not return to the game. Head coach Todd Monken said he had no update on Graham’s condition during a postgame press conference, but Mary Kay Cabot of Cleveland.com reported that Graham left the stadium on crutches while wearing a brace on his knee.

There will likely be further testing of the injury on Friday and the Browns will be hoping for good news about a player who had four sacks in the first three weeks of the season.

Graham’s absence did not stop the Browns from finishing the night with five sacks of Aaron Rodgers. Mike Hall and Maliek Collins each had one of them and that duo will be crucial to the Browns defense if Graham is out of the lineup moving forward.
