Jay Ajayi (concussion) limited at practice

[DKphin]

Jay Ajayi. is still in concussion protocol, but he was on the field with his pads and helmet on, catching passes from Cutler, NFL Network's Tom Pelissero reported. Ajayi is not cleared for game action, but having him on the practice field is a positive sign for the running back's progression.

Being pre-season, I think they are probably being overly cautious.
