Cleveland Browns cornerback Denzel Ward was diagnosed with a concussion following Sunday's 26-18 win over the Cincinnati Bengals, according to Nate Ulrich of the Akron Beacon Journal.
He had five tackles in the win before heading to the locker room, including one for a loss.
The rookie returned to the field Sunday after missing the previous two games with a concussion, so the latest injury is certainly a significant concern.
Tony Grossi of ESPN Cleveland noted this was the second concussion in three weeks after never previously dealing with this type of problem.
