Defensive tackle Gervon Dexter, who leads the Bears with five sacks this season, was ruled out of Monday's game against the Vikings after missing practice all week with a knee injury.
Dexter, who has started all 13 games for the Bears this season, was one of three Bears ruled out after Saturday's practice. Running back Roschon Johnson and guard Ryan Bates have concussions.
Running back D'Andre Swift is questionable with a groin injury. The other three Bears who missed practice time with injuries this week — cornerback Josh Blackwell, safety Elijah Hicks and running back Travis Homer — will play.
The Bears have struggled to pressure the quarterback all season. Their 31 sacks rank 19th in the NFL. Dexter ranks ahead of defensive end Montez Sweat in sacks. Sweat, whom the Bears gave a contract extension after trading for him last year, has just 4 1/2. Only two other Bears have more than two.
