Jets' Jeremy Kerley has concussion

FLORHAM PARK, N.J. -- New York Jets wide receiver Jeremy Kerley, who was cleared to return to Sunday's game after a blow to the head before halftime, was diagnosed Monday with a concussion, according to a team spokesman.

Kerley's helmet flew off on an eight-yard reception when he was sandwiched by a trio of Tampa Bay Buccaneers -- Leonard Johnson, Dashon Goldson and Mark Barron. Barron was penalized for unnecessary roughness. On the previous series, Goldson was penalized for a similar hit on tight end Jeff Cumberland.

Kerley went to the locker room and was permitted to return after passing the mandatory concussion test, said the spokesman, adding that Kerley also passed a postgame evaluation. He ended up playing 39 offensive snaps in the game.

On Monday, Kerley exhibited symptoms during an evaluation and was held out of practice after the diagnosis, according to the team. He likely won't play Thursday night against the New England Patriots.

Kerley's absence would be felt in two ways. He's the slot receiver, playing in three-receiver packages, and their top punt returner. Without Kerley, they'd be down to four receivers, three of whom are nursing minor ailments – Santonio Holmes (foot), Stephen Hill (knee) and Clyde Gates (knee). Kyle Wilson probably would replace Kerley as the punt returner.

The Jets came under scrutiny last season for allowing running back Shonn Greene to return to a Week 2 game in which he was dazed and wobbly after an illegal helmet-to-helmet hit by Pittsburgh Steelers safety Ryan Mundy. Greene was cleared to return after passing a concussion test in the locker room, later telling reporters he had no recollection of quarterback Mark Sanchez pushing him toward the sideline after the hit.
