Chicago Bears' fans, coaches and analysts will get their first real look at quarterback Justin Fields. 

With Andy Dalton sidelined, Fields will take over under center and be the starting quarterback. 

While expectations will be high, it would likely take Fields a couple of games to get fully comfortable and roll through an NFL team. 

However Fields is a gamer and he's ready. 

"I've been preparing for this moment for a long time," Fields said. "My mindset doesn't change. I'm still going to have to play my football and just prepare the best I can. Like I said before, get a lot of practice reps and study, study, study, and get more comfortable and confident with the plays and stuff like that."

Regardless of how Fields does, it seems that Dalton will still be the starter according to head coach Matt Nagy.
