TWO BITS: Harvin’s migraines, Tebow’s workouts

1 » Could former Florida Gators wide receiver Percy Harvin be sitting out the most important game of his young NFL career? If his sudden migraine flare-up continues, he just might. Harvin missed Minnesota Vikings practice on Thursday [and Friday] for the first time since returning from the Mayo Clinic in December. He had been headache-free for more than a month, but head coach Brad Childress indicated that the only thing that can cure Harvin is time. “I think it’s just a matter of trying to slow the onsets,” Childress said. “For a while he had them pretty often. We expect him to be OK.” Harvin has 60 receptions on the season, second on the team to Sidney Rice, and has become one of quarterback Brett Favre’s favorite targets on third down.

2 » Preparing for the 2010 Under Armour Senior Bowl and a future in the NFL, former Gators quarterback Tim Tebow has been working out in Franklin, TN, since last week at D1 Sports Training. Co-owned by Indianapolis Colts star QB Peyton Manning, D1 “specializes in making athletes faster, stronger, more agile and explosive while also building character,” according to the company’s mission statement. Tebow is working closely with former Georgia Bulldogs All-American QB Zeke Bratkowski, a 40-year playing and coaching veteran. “When they see him in person, how he moves and throws, his work ethic at the Senior Bowl, and his passion for the game, I think that is what is going to move him up on the draft,” said Kurt Hester, director of training for D1.
