Vikings coach Brad Childress said rookie Percy Harvin missed practice Thursday because of a "headache."
Harvin's history with migraines is well-documented. He missed one game this season because of a severe bout. Harvin visited the Mayo Clinic recently and said he came away with a good game plan for how to deal with his migraines.
Harvin had not experienced any problems since meeting with Mayo doctors. "I think it's just a matter of trying to slow the onset," Childress said.
