Dolphins RB Jay Ajayi being evaluated for concussion

DAVIE, Fla. - Miami Dolphins Pro Bowl running back Jay Ajayi is being evaluated for a concussion and was unable to finish practice Monday, according to head coach Adam Gase. The team will not have a confirmed diagnosis on Ajayi until later this afternoon, Gase said.

Ajayi got a lot of work in Miami's first full-contact, full-padded practice of training camp. He ran the ball and caught several passes out of the backfield while taking some hits in the process. Dolphins safety T.J. McDonald, for example. had a big hit on Ajayi that knocked the tailback off his feet in one of Ajayi's final plays.

This is the first potentially scary injury for the Dolphins in training camp.

"You're not going to win either way," Gase said. "If you don't go live, you're going to dread that you don't work on tackling. If you go live and somebody gets hurt, you going to say you shouldn't. It doesn't matter. You're going to be wrong either way. We feel like that's best for our football team. We need to go live and tackle. That's football."

It is vital for Ajayi, who led the Dolphins with 1,272 rushing yards, to stay healthy this coming season. Gase said earlier in the offseason that he will not be afraid to give Ajayi 300 carries if necessary, and the running back has worked diligently catching passes out of the backfield.

Monday's practice also was a good example of how much work Ajayi could get this season in his quest to become a better three-down running back.
