Minnesota Vikings wide receiver Percy Harvin is fighting another migraine headache. Coach Brad Childress said Wednesday that Harvin was not at team headquarters. After a severe outbreak kept him out of practice for most of August, Harvin was diagnosed with sleep apnea and given a breathing machine to use while he sleeps. The migraine episodes since then have been far less frequent. Harvin played in last Sunday's game with a sprained left ankle, finishing with a career-high nine catches for 126 yards in the overtime win over Arizona. Source: Associated Press
