So far in Arizona Cardinals running back Ryan Williams young career, he has had many injuries problems which has not shown off his full potential that he showed off at Virginia Tech. Williams, who has an achy right knee which might be coming from tearing his patella tendon nearly two years ago is now receiving PRP injections.

If you don’t know what PRP injections are, they are platelet-rich plasma injections. Other athletes such as Los Angeles Lakers guard Kobe Bryant and New York Yankees third baseman Alex Rodriguez have gotten these injections before. Williams got the injections in his right knee about 10 days ago and it takes about two weeks before he or anybody can get back into action.

The Cardinals play the Dallas Cowboys on Saturday so don’t expect Williams to play since that would be the exact two week mark.

According to the Arizona Republic, Dr. Luga Podesta, an orthopedic surgeon at Kerlan-Jobe Orthopaedic Clinic in Los Angeles, said about the PRP injection process:

"It works like this: The patient’s blood is drawn and then put through a centrifuge. That concentrates it down to 7-10 times the normal amount of platelets. The substance is then injected into the injured area. “It tricks the body into regenerating.”"

Hopefully, the PRP injections work well for Williams because with him and Rashard Mendenhall in the backfield, it could give the Arizona Cardinals a good one-two punch.
