The Chicago Bears played twithout starting quarterback Mitchell Trubisky during Thursday's 23-16 win over the Detroit Lions.
Trubisky was officially inactive because of a shoulder injury he sustained in Week 11's win over the Vikings.
Backup signal-caller Chase Daniel got the start.
The short week of preparations also played a role in the decision, as NFL Network Insider Ian Rapoport noted Trubisky could probably play if this were a Sunday game.
The Bears conducted a walkthrough practice Wednesday and officially listed Trubisky, who was estimated as not practicing, as doubtful to play.
