Vikings receiver Percy Harvin is listed as questionable for Sunday's home game against Arizona, leaving Minnesota with three healthy receivers.
Harvin sprained his left ankle last weekend against the New England Patriots, but remained in the game and finished with five catches for 65 yards. He missed practice on Wednesday and Thursday. Coach Brad Childress said he practiced "on an extremely limited" basis on Friday.
Harvin, who has also played after battling migraine headaches, was unavailable for comment on Friday.
"You know, he's a tough guy. Let's face it," Childress said. "He injured that foot on his first catch of the game and still was very productive. I would just say that he's tough. Different things respond different ways. Everything goes through your foot and your ankle so he's got to have his faculties for the game the way he plays it."
