The former first-round pick out of Ohio State ran for a career-high 1,047 yards on 245 carries in 14 games.

He did a lot to dispel to the label that he couldn't play through pain, too, often excelling despite being bothered by a knee injury for a good portion of the season.

Wells had right knee surgery on January 24 to repair a torn meniscus and more, and hasn't participated in OTAs or minicamp, which concluded Thursday afternoon. With only 41 days between the conclusion of minicamp and the first training camp practice in Flagstaff, there seems to be growing concern about Wells' readiness.

"He's got to to work himself back into being ready, and I think that's an important thing," head coach Ken Whisenhunt said Thursday. "We've done the right thing with Beanie, as far as the offseason about making sure he's healthy and trying to get him ready.

"He's gotta bust his tail over the next few weeks to be ready for training camp because we've had some guys look good there."

One of those guys is second-year back Ryan Williams, who has been limited himself as he is returning from a gruesome knee injury suffered during a preseason game last August. Williams got three carries during 11-on-11 drills during Wednesday night's Fan Fest at University of Phoenix Stadium in what was his first full-speed work since the injury.

"That was a big hurdle (Thursday) night, so I expect him to be ready to go in training camp," Whisenhunt said. "We're not going to throw him in there and give him every rep. We're going to make sure we continue with the process of getting him ready for the first game."

Despite the Cardinals' top two options at running back recuperating from knee surgery, Whisenhunt feels good about his personnel at the position.

"It doesn't concern me right now, we've still got a number of weeks until training camp starts," Whisenhunt said. "We've seen Beanie rush for over a thousand yards, we know what LaRod [Stephens-Howling] is, we expect to have Ryan back, so once we get to training camp and we get those guys going, I don't think I'll have any concerns."
