Minnesota Vikings wide receiver Percy Harvin didn't practice Thursday because of an all-too-familiar reason. Harvin is trying to get over his latest case of migraine headaches. He was limited in Wednesday's practice before being absent. Of course, interim head coach Leslie Frazier would like to have him back on the field as soon as possible; he's just not sure when that will happen. "Hopefully we can get him [Friday]," Frazier said of Harvin. "We'd like to, but we'll see what happens. It's migraine-related. He's having some episodes, so we've just got to see how things go." Harvin has experienced these migraines since he was a child. He missed a game last season and has been missing numerous practices because of them.

Fantasy Analysis:

We'll see if Harvin can practice Friday. As always, Harvin's status is completely unpredictable when he's going through these migraines, but they can clear up at any time. Even if Harvin plays, he's not an elite start. He hasn't put up much yardage in the past three games -- 64 is his most since week nine. Now the Buffalo Bills come calling, a bend-but-don't-break secondary. It's a matchup that is no better than Harvin's last opponent, the Washington Redskins. Percy accumulated just 32 yards in that game. With Adrian Peterson banged up, Harvin may get some extra looks, but he's a fairly risky WR3 this week with limited upside. You can thank Brett Favre for most of that opinion.
