UPDATE: Khalil Mack later returned to the game for the Bears. 

Chicago Bears star pass rusher Khalil Mack left the Week 3 matchup against the Cleveland Browns and went to the locker room with a foot injury. Mack went to the medical tent after playing the first two series of the game and then walked to the locker room.

Mack is officially questionable to return. He later returned from the locker room to the bench and looked like he had a limp, so that doesn't seem like a good sign in terms of him returning to the game.

Mack sacked Baker Mayfield before leaving Sunday's contest. The Bears' defense held strong against the Browns in the first quarter, stopping them on fourth down multiple times. One of those stops was Mack's sack of Mayfield.

Sunday's Week 3 affair is Justin Fields' first NFL start, but he hasn't had much of a chance to do anything. The rookie has been under constant pressure from the Browns' defensive front. Mayfield hasn't done much either for Cleveland, so this has been an ugly one so far as both defenses have stood strong.

The Bears and Browns both entered Sunday's game with a 1-1 record. Chicago got destroyed by the Los Angeles Rams on Sunday Night Football and then beat the Cincinnati Bengals in Week 2. Cleveland lost to the Kansas City Chiefs to open the season and then beat the Houston Texans last weekend.
