The Bears worst fears have been confirmed. Coach John Fox tells reporters that linebacker Danny Trevathan is done for the year with a knee injury. Specifically, it’s a ruptured patella tendon that will end Trevathan’s season early, according to Ian Rapoport of NFL.com (on Twitter). The Bears will place Trevathan on IR, opening up a spot on the 53-man roster. 
This has been a trying season for the Bears, to say the least. After a rocky start to the year, quarterback Jay Cutler found himself on the sidelines for several weeks with a sprained thumb. Then, running back Jeremy Langford was put out of commission for multiple games thanks to an ankle injury. Then, as the losses continued to pile up, the Bears found out that wide receiver Alshon Jeffery and linebacker Jerrell Freeman were both slapped with four-game bans for PEDs. Now, Trevathan becomes the 15th member of the team to go on IR as the 2-9 Bears continue to struggle.
Trevathan, 26, was productive during his first season in Chicago. As of this writing, he is second on the team in tackles (61) and he also has a sack and four passes defended. Even more impressive, he did this while missing two of eleven possible games thanks to his September thumb surgery. The Bears still have the former Bronco under contract for another three years beyond 2016.
