Trubisky was a full participant in practice this week, and coach Matt Nagy has said Trubisky will start if medically cleared. Trubisky suffered the injury early in the Bears' win against the Vikings on Sept. 29 and missed Chicago's loss to Oakland in London on Oct. 6.
The Bears prepared backup quarterback Chase Daniel with appropriate reps in practice this week for the chance Trubisky is unable to return Sunday.
The Bears also listed guard Ted Larsen (knee) and defensive lineman Bilal Nichols (hand/knee) as questionable. Receiver Taylor Gabriel (concussion) and linebacker Joel Iyiegbuniwe (hamstring) weren't listed with a game status and are expected to play.
The Saints officially ruled out star running back Alvin Kamara (knee/ankle) and tight end Jared Cook (ankle). Quarterback Drew Brees (right thumb) was also ruled out, as expected.
Kickoff between the Bears (3-2) and Saints (5-1) comes at 3:25 p.m. Sunday from Soldier Field. The game can be heard on WBBM Newsradio 780.
