EDEN PRAIRIE, MINN. (AP) - Minnesota Vikings wide receiver and kickoff returner Percy Harvin is doubtful for Sunday’s game at Chicago because of lingering migraine headaches.

Harvin had his helmet on and took part in drills Friday after absences the previous two days. Harvin has played through the condition several times before, but coach Brad Childress said the episode “hasn’t completely cleared yet” and that he will list Harvin on the injury report as doubtful to play against the Bears.

The NFL defines the designation as having a 25 percent chance to play.

The availability of fellow wide receiver Sidney Rice for the Bears game is still uncertain. Childress called Rice questionable, though he’s still on the physically unable to perform list and won’t appear on the official injury report.
