Vikings coach Brad Childress said Tuesday on Sirius NFL Radio that Percy Harvin seems to be better this week after the rookie wide receiver sat out last Sunday's game against Cincinnati because of migraine headaches. "He should be back and at it [Wednesday] when we start practice but the process is not over yet," Childress said.

Harvin has dealt with migraines since he was 10 years old and has missed practice time at points this season but the problem hadn't kept him out of a game until Sunday. Despite Harvin's improvement, Childress said: "We're working vigorously to try to address [the issue] and take some testing and that type of thing, which I'm sure he's gone through before."

Childress added that Harvin spent "a bunch" of Monday going through tests, an indication that he saw a doctor. Harvin also saw a doctor last week as he missed all three days of practice because of migraines for the first time this season.
