LAKE FOREST, Ill. (CBS) — As it turns out, there was another thumb of great concern at Halas Hall.

Bears linebacker Danny Trevathan will require surgery for a right thumb sprain suffered in Monday’s 29-14 loss to the Eagles. He’s out indefinitely, though head coach John Fox stated that it won’t be a season-ending injury. Trevathan joins quarterback Jay Cutler on the sidelines with a thumb injury as the Bears look to rebound from an 0-2 start.

Trevathan left the game in the third quarter briefly and had his right hand examined. Backup Jonathan Anderson assumed his place at inside linebacker alongside Jerrell Freeman. Trevathan later returned to action and stayed in for the remainder of the game. He wouldn’t state what the injury was after the game.

Without Trevathan in the fold, it will be Anderson starting at inside linebacker. The Bears wouldn’t place Trevathan on IR, Fox said, which would allow a return in six weeks with the “short-term” designation.

Fox came to the podium Tuesday and said that there was “not a whole lot to update” on the injury report, then he went through a long list that included the surprising Trevathan news. The Bears’ injury report also includes Cutler, whose thumb sprain won’t require surgery; defensive lineman Eddie Goldman, whose ankle sprain is still being evaluated; linebacker Lamarr Houston, whose knee injury is considered “substantial” as the team awaits an MRI; and safeties Adrian Amos and Bryce Callahan, both of whom are in the NFL’s concussion protocol.

Additionally, safety Chris Prosinski suffered a calf injury and running back Ka’Deem Carey is dealing with a hamstring injury.

Adding to the Bears’ problems, they now face a short week ahead. After taking the Monday night spotlight, they face a quick turnaround for Sunday’s primetime contest with the Cowboys in Dallas.

The Bears will take the practice field on Wednesday at Halas Hall without several of their most important players.
