Harvin’s headaches keep him out of practice again

Minnesota wide receiver Percy Harvin has missed another practice

while struggling with migraine headaches.

Harvin was absent again Thursday as the Vikings prepared to play

Carolina in a Sunday night game. The rookie also sat out last week

against Cincinnati.

With toughness as a runner and pass catcher and straight-ahead

speed as a kickoff returner, Harvin has given the Vikings a big

lift since he was drafted in the first round this year.

Medical experts say migraines are difficult to treat and

predict. Many times, people who suffer them can only lie in a dark,

quiet room until the pain goes away.
