Jets head coach Robert Saleh said Monday that Riley has been placed in the NFL's concussion protocol, Rich Cimini of ESPN.com reports.
Riley's diagnosis comes as no surprise after he was stretchered off the field upon suffering a neck injury in Sunday's loss to the Dolphins. Fortunately, he checked out fine after the contest and had full motion of his extremities, so clearing the five-step concussion protocol will be his main focus as he aims to return to game action. Saleh said he expects Riley to return at some point over the Jets' final three games, perhaps even as soon as the team's Week 16 matchup with Jacksonville.
