Dexter McCluster was at the height of his powers last Sunday, setting a Kansas City Chiefs record with 177 punt-return yards -- including a 74-yard touchdown -- in a blowout win over the Washington Redskins.

Five days later, McCluster is battling an ankle infection that has left him questionable for Sunday's matchup against the Oakland Raiders. McCluster suffered a small cut on his ankle during the Washington win, and complained of swelling in the area after Wednesday's practice. He was held out of practice the next two days.

An MRI and scan ruled out structural damage. McCluster underwent a minor procedure to open and clean the wound before he was placed on IV antibiotics.
