CHICAGO (670 The Score) -- Bears linebacker Danny Trevathan suffered what appeared to be a gruesome injury to his left elbow during the first quarter against the Lions on Sunday.
Trevathan was injured hitting Lions quarterback Jeff Driskel on a pass with 4:16 remaining in the first quarter. His left arm bent in reverse as he landed awkwardly. Trevathan immediately ran off the field to the Bears' sideline. He was evaluated in the team's medical tent before leaving to the locker room.

The Bears later officially ruled Trevathan out. Nick Kwiatkoski assumed his role at inside linebacker, lining up alongside Roquan Smith.
Trevathan, 29, had three tackles Sunday at the time of his injury, which brought his total to 51 over nine games this season. He's playing the final season of a four-year contract with the Bears.
The Lions led the Bears 3-0 at the time of Trevathan's injury. More updates will be provided as they're made available.
