EDEN PRAIRIE, Minn. (AP) -Minnesota Vikings rookie receiver and return man Percy Harvin did not practice Thursday because of illness.

Coach Brad Childress did not specify the illness, but Harvin has had trouble with migraine headaches this season. Childress says he is hopeful that Harvin will return to practice Friday, two days before the game at Green Bay.

Receiver Bernard Berrian and linebacker E.J. Henderson missed practice for the second straight day. Berrian has an injured hamstring and Henderson is dealing with a knee injury.

Cornerback Antoine Winfield continued to miss practice while he recovers from a foot injury.
