(670 The Score) The Bears have ruled nickel cornerback Buster Skrine out against the Vikings on Sunday as he remains in the concussion protocol, while rookie cornerback Jaylon Johnson is questionable to play because of a right shoulder injury.

Johnson suffered the injury in a win against the Texans last Sunday when he tackled quarterback Deshaun Watson just before the goal line. The injury is to the same shoulder that Johnson had surgically repaired this past offseason. Johnson didn't practice this week.

The Bears will likely turn to Duke Shelley at the nickel cornerback position. Rookie Kindle Vildor would replace Johnson if he's unable to play.

Bears star pass rusher Khalil Mack (shoulder) is questionable. Mack dealt with this shoulder injury last week before playing Sunday. Tight end Jimmy Graham (hip), safety Deon Bush (foot) and linebacker James Vaughers (knee) are also questionable.

Kickoff between the Bears (6-7) and Vikings (6-7) comes Sunday at noon from U.S. Bank Stadium in Minneapolis.
