Minnesota Vikings WR Adam Thielen leaves with head, neck injuries

MINNEAPOLIS -- Minnesota Vikings wide receiver Adam Thielen left Sunday's game in the third quarter with head and neck injuries, after a hard hit by Indianapolis Colts cornerback Darius Butler.

Thielen appeared to catch a long pass from Sam Bradford when he was hit high and hard by Butler and dropped to the turf, with the ball rolling away. The pass was ruled incomplete, but Butler was penalized 15 yards for unnecessary roughness on the play.

Thelen started the game but did not have a reception.
