CHICAGO (CBS) — Lamarr Houston and Victor Cruz, two vested veterans fighting for roles with the Bears, left Thursday’s preseason game with knee injuries.

Coach John Fox didn’t know the extent of both injuries after the game, a 25-0 Bears loss to the Browns at Soldier Field. Both will be evaluated further on Friday.

Houston suffered a torn ACL during the second game of last season. He also suffered a torn ACL during the 2014 season.

Houston was playing out the second half because the Bears are lacking depth at outside linebacker, while Cruz has found himself working for a roster spot ahead of Saturday’s cut-down deadline.

The Bears also lost Deon Bush, Deiondre’ Hall and Connor Shaw to hamstring injuries.
