Harvin had missed Thursday’s practice because of an illness but it isn’t believed to be caused by migraines.
“We know there’s a distinct difference what’s happening with your stomach and what’s happening with migraines,” Frazier said. “… We fully expect him to be back out here (Friday) ready to go. He should be fine.”
The Vikings have addressed the concerns about Harvins playing time by mentioning that they intend to expand his role in the teams offense.
“We’ll want to keep growing (Harvin’s) package so we can get more production out of our entire offense,” Offensive coordinator Bill Musgrave said.
