Adrian Peterson looked impressive in his first practice after nearly nine months away from the Minnesota Vikings.

"I haven't been around him a year, or six months. I didn't know he'd come back in this type of shape," cornerback Captain Munnerlyn said. "The guy is in unbelievable shape, like he hadn't missed a step, and he's out to prove a point."

Offensive coordinator Norv Turner said Peterson retained a large section of the Vikings' offense after his time away from the team and has been eager to learn the new concepts the Vikings are adding to their offense.

"I've been around a lot of these guys a lot of years, and he's one of the top guys I've been around," Turner said. "He just comes out and looks like he hasn't missed a day. It was nice having him."
