What happened: Chicago announced with the game in progress and the Bears holding a 27-21 lead that defensive back Malik Muhammad is doubtful to return due to a toe injury. Mike Garafolo noted that the rookie fourth-rounder has been a major part of the team's secondary so far this season.

Why it matters: Losing a regular contributor in the defensive backfield mid-game tests the secondary depth of the defending division-champion Chicago Bears as they work to protect a live lead.

What to watch: Chicago will address Muhammad's status after the game in progress concludes.
