What happened: Goaltender Jacob Fowler takes the crease for Friday night's game in Chicago while defenseman Mike Matheson re-enters the active defensive rotation. To accommodate Matheson's activation on the back end, Adam Engstrom will be scratched from the lineup.

Why it matters: Getting Matheson back restores a veteran presence to the defensive pairings after his recent stint out of the lineup. Giving Fowler another regular-season start tests the young netminder on the road while cycling Engstrom out of the six-man unit.

What to watch: Puck drop in Chicago will show how Matheson handles his regular-season workload upon returning to game action and how Fowler performs between the pipes.
