Update: Chicago Bears head coach Matt Nagy told reporters after Sunday's win against the Cincinnati Bengals that starting quarterback Andy Dalton will have an MRI Monday on his injured knee, but Nagy said he's pretty sure the long-time Bengals starter did not suffer an ACL injury.
Earlier: The Chicago Bears replaced starting quarterback Andy Dalton with rookie Justin Fields after Dalton tweaked his knee at the end of a second-quarter run Sunday against the Cincinnati Bengals.
The Bears announced late in the first half that Dalton was questionable to return to the game with the knee injury. Late in the third quarter, Dalton was downgraded to doubtful.
He did not play in the second half of the Bears' 20-17 win.
Dalton, who led the Bears to a touchdown on their opening drive of the game, was seen limping on the sideline after the play. The Bengals stopped Fields and the Bears on fourth down a couple of plays later.
Dalton was examined, but was able to jog and drop back to test out the knee on the sideline. He returned for the Bears' following series, but he walked to the locker room after it.
"First of all, let's find out how bad Andy's hurt. If (Fields) comes in and plays well - and they win the football game - more than likely he will definitely start the following week," Terry Bradshaw said during FOX NFL's halftime show.
