Harvin ill, no migraine, Frazier said

Coach Leslie Frazier said Percy Harvin missed practice because he's ill, not because of a migraine.

Harvin is expected back at practice on Friday, Frazier said.

Harvin has battled migraines off and on since he was 10. Asked if this was another migraine, Frazier said, "No, no. Just wasn't feeling well and thought it best to hold him back today, but we fully expect him to be back out here tomorrow ready to go."

Frazier said Harvin's illness "may be a virus, but he should be fine."

Asked how the team can be sure it's not a migraine, Frazier said, "Yeah, from everything I'm being told. ... There's a difference. We've gone through the migraines. There's a distinct difference with what's happening with your stomach and what's happening with migraines."

Frazier said Harvin's history with migraines isn't a factor in his number of snaps.

Harvin was in meetings earlier today and wasn't feeling good. So he was sent home.

CB Chris Cook (groin) and LB E.J. Henderson (knee) were limited in practice, while DE Jared Allen (shoulder), CB Marcus Sherels (chest), CB Asher Allen (toe), WR Michael Jenkins (groin) and DT Kevin Williams (foot) had full participation.

On Cook, Frazier said, "He was able to finish practice. He seemed like he moved pretty well in practice today. We'll see how he feels when he wakes up tomorrow. But he moved pretty good."
