Bills WR Easley leaves game for concussion test

FOXBOROUGH, Mass. (AP) Buffalo Bills receiver Marcus Easley has left Monday night's game against the New England Patriots with a head injury.

The Bills said he would undergo testing for a concussion and would not return.

The NFL's handling of concussions is under increased scrutiny after St. Louis quarterback Case Keenum was knocked woozy during Sunday's game against the Baltimore Ravens. He remained in the game, but fumbled two downs later.

The league said Monday it would investigate whether its protocol was followed.

Later in the first half, offensive lineman John Miller was carted off the field with an injury. The team said he had an ankle injury and it was questionable whether he would return.

Patriots receiver Aaron Dobson limped off the field after making a catch in the second quarter. The team said he had an ankle injury and it was questionable whether he would return.
