Chicago Bears quarterback Mitch Trubisky missed Week 12 due to a shoulder injury and there's been various speculation regarding it. 

Original reports were that if the Bears had played on Sunday instead of Thursday during Week 12, Trubisky would have started. 

Then a report came out that Trubisky could actually miss multiple weeks, and now it seems that his Week 13 status is definitely in doubt. 

Bears head coach Matt Nagy told NFL Network's Ian Rapoport that Trubisky is currently day to day and the team is still unsure if he can play Sunday. 

Nagy added that the team will take the same approach that they did with Khalil Mack and hold him out if they feel it's the better thing to do. He added there's absolutely no rush to get the QB back on the field and that Chase Daniels did a great job in Trubisky's absence.
