CHICAGO (AP) - Minnesota Vikings center John Sullivan and safety Jamarca Sanford have left Sunday’s game against the Chicago Bears because of concussions.

Sullivan was on the field for the Vikings‘ first series in the third quarter and then left the game. Sanford left midway through the quarter.

It was not clear how either injury happened.

Chicago tight end Kellen Davis injured an elbow, and is also out for the game.
