Donnell left Monday's game against the Vikings with a concussion, and he will not return to the contest, Seth Walder of the NY Daily News reports.
Donnell was a step slow to his blocking assignment on a running play, which allowed Vikings LB Anthony Barr to come through the hole and lay a huge hit on the tight end. It was obvious when watching the play that Donnell suffered a concussion, and he was ruled out for the rest of the night almost immediately thereafter. Will Tye, who typically splits snaps with Donnell, will take on an expanded workload for the rest of the night.
