The Pittsburgh Steelers believe linebacker Bud Dupree suffered a torn ACL in Wednesday's win over the Baltimore Ravens.

Dupree injured his left knee on a noncontact play in the second half. Further testing is expected to confirm the injury on Thursday.

"I think it was very quiet, very sad, very low, just because having our fellow teammate going down, Bud, and not knowing what's going on over there," wide receiver JuJu Smith-Schuster said, describing the Steelers' locker room after the game. "But that's something that, you always pray for everybody to be safe and have a healthy game."
