Vikings wide receiver Percy Harvin is battling another migraine headache today and is not at Winter Park, according to coach Brad Childress. Harvin visited with doctors this morning.

Harvin, who had a career-high nine receptions for 126 yards in the Vikings' overtime victory last Sunday over Arizona, has battled migraines for much of his life and missed almost all of training camp because of issues with the headaches following the death of his grandmother.

Harvin went to the Mayo Clinic in Rochester, Minn., last winter to be examined and was confident this season that the problem was under control after doctors in the Twin Cities diagnosed him with sleep apnea.

Harvin and Childress got into a heated argument last Friday during practice and sources said that Childress had questioned Harvin's efforts.

Childress denied that was the case and said the disagreement was about the fact Harvin hadn't had an MRI on his sprained left ankle. Harvin, who had been hurt the previous Sunday at New England, had the procedure performed on Saturday.

Etc.

  • The Vikings signed cornerback Cord Parks to their practice squad to replace Colt Anderson, who has been signed to the Eagles' 53-man roster. Parks (Northeastern) has spent time with St. Louis and Seattle.
  • Reports are circulating that Sidney Rice could play Sunday against Chicago, but Childress was not willing to confirm that the wide receiver is ready to go.
  • Quarterback Brett Favre appears to be getting another Wednesday off as he is allowed to rest his injured left ankle and heel. Safety Jamarca Sanford (hamstring), cornerback Asher Allen and Harvin also are not practicing. Allen was on the injury report last week with a back issue but he did not miss practice time.
