Percy Harvin was absent again as he continues to battle the migraine headache that prevented him from playing on Sunday, apparently had cleared on Monday and then resurfaced again sometime before the Vikings resumed practice on Wednesday.
"Still just doing what he has to do," Frazier said. "We'll just take it slow with him."
Harvin was not at the team facility at all on Thursday, according to Frazier, who had expressed optimism on Wednesday about his leading receiver's chances for playing.
Asked if Harvin had a setback, Frazier said, "We were hoping that he'd be able to do something (Thursday). The fact that he couldn't just means we'll move it back another day. Friday's not the end of the world. If he can do some things (Friday), that will be great, and hopefully, that will be the case."
