Long road back for Ryan Williams, others

By Mike Sando

The injury Ryan Williams suffered during his second NFL exhibition game was relatively unusual for football players.

"My kneecap was in my thigh," the Arizona Cardinals' running back said during a team-produced video on his rehabilitation. "It was just kind of like, 'What?' "

A torn patella tendon ended Williams' rookie season before it officially began.

The running back expects to return for training camp and the 2012 regular season. Cadillac Williams and Earnest Graham returned from similar injuries, but each situation is different. The Cardinals cannot know how the knee will respond. No one can.

Cadillac Williams returned, only to injure his other knee. Suffering a second injury so quickly complicated comparisons to other running backs returning from a single torn patella.

Ryan Williams is not yet even 22 years old, however.

"He has youth on his side, for sure," ESPN injury expert Stephania Bell said Thursday. "What you worry about is, it takes a lot to get any kind of explosiveness or power back. You're not talking about strength, but quickness."

Williams, a second-round choice from Virginia Tech, impressed the Cardinals with his ability to change directions without losing much speed.

"It is reasonable he could be back when the season starts," Bell said, "but will he really be back? That is going to remain to be seen and like these guys coming off ACL surgeries, it may take a while to see what his max is that he can return to."

The Cardinals need Williams in part because their primary back, Beanie Wells, has struggled with injuries, fighting through knee trouble last season after undergoing surgery.

Four additional injury situations to monitor, one per NFC West team, as the offseason continues:
