Chicago Bears receiver Alshon Jeffery went down with leg cramp in the team's first rookie minicamp workout on Friday.

Trainers came out to stretch out Jeffery, but the 6-4, 229-pound second-rounder out of South Carolina couldn't continue and was taken off the field for precautionary reasons. He's expected to be fine.

"[He was just] cramping up," Bears head coach Lovie Smith said. "Guys do a lot of working out on their own, but it's not like when you come here and work out. I really liked what Alshon did earlier in practice, for most of the practice really. I didn't see him drop a ball. He's got great hands, is a big target and really liked the way he came in. He's going to be a good football player for us."

Offensive coordinator Mike Tice also was impressed with Jeffery.

"I saw him make a few plays over there in the one-on-ones," Tice said. "Back in the day, we called that 'picking peanuts.' He was picking peanuts off some guys’ heads it looked like to me. So I think he’s gonna have the ability for us to make plays.

"You could tell he has some explosiveness about him. You could tell he has some ball skills. That’s why we drafted him so high. You can tell that he’s gonna be a playmaker for the Bears for 2012, and hopefully for many years to come."
