New York Jets first-round safety Calvin Pryor sustained a concussion in practice, coach Rex Ryan confirmed Sunday.
Ryan said the rookie was injured in a special teams drill on Saturday while blocking on a kick return.
"Pryor now will go through the protocol, so it is a concussion," Ryan said, according to the New York Daily News. "Apparently it was on a kick when we were doing a kick return drill and he was blocking and the returner kind of got knocked into him and kind of just hit him right. It's one of those things. One of those heavyweights hit you in the chin, the lights go out I guess."
Ryan said he wouldn't hesitate to play starters on special teams.
"When you look at it, we're going to play them all," Ryan said. "We're going to have a bunch of those guys on all our special teams. ... We think we have to get better on teams, we want to be one of the top special teams units in the league. It's really all hands on deck."
