NFL notes: Harvin's migraine attack scares Vikings

Percy Harvin experienced the scariest episode yet in a career plagued by migraine headaches when he collapsed at Minnesota Vikings' practice Thursday and was taken to a hospital by ambulance.

Coach Brad Childress left team headquarters after practice and spent the rest of the afternoon at the hospital with Harvin, who also got visits from other coaches and teammates.

"Percy appreciates everyone's concern," the coach said in a statement posted on the team Web site Thursday evening. "He is alert and resting comfortably, but will remain in the hospital overnight."

Harvin, who has dealt with migraines most of his life, returned to the field Monday after missing more than two weeks, but at the beginning of Thursday's workout the wide receiver experienced another episode that was scary enough for the Vikings to halt practice while their teammate received medical attention.

Childress said that Harvin's episode was triggered when he looked up into a mostly cloudy sky to field a punt during a special teams drill. Soon after, Harvin was seen doubled over and trembling. Players and coaches stood in front of him to shield him while reporters watched from a distance as Harvin received medical attention.

"I think by this happening it kind of lets the team know exactly how hard it is," left tackle Bryant McKinnie said. "A lot of times it doesn't take place in front of us. So now by people actually seeing it, they see it's really not a joke."

Broncos coach endorses Tebow's aggressiveness

Tim Tebow's battered ribs are casting doubt and raising concerns in Denver. The rookie quarterback is questionable for his home debut with the Broncos on Saturday night after missing two practices this week. More importantly, will Tebow have to alter his physical style of play now that he's in the bigger, badder NFL?

Tebow was known for running the football at Florida, where he won two national titles and a Heisman Trophy, and he never really had to slide or go out of bounds much in college, where at 6-foot-3 and 245 pounds, he was bigger and stronger than many of his pursuers.

However, he's still adjusting to the faster pro game and he absorbed some vicious hits in his debut Sunday night at Cincinnati. Tebow evidently suffered bruised ribs on the game's final play when Bengals linebacker Abdul Hodge blasted him on his left side as he scrambled into the end zone for a 7-yard TD.

Broncos Coach Josh McDaniels said Tebow's aggressive style is what gives him a chance to succeed in the NFL, and he won't try to coach that out of him.

"To judge him on what happened the other night in terms of being reckless I would say is very unfair," McDaniels said. "What he did the other night I hope all of our guys would have done, no matter who it was."

Around the league

Giants: Backup quarterback Jim Sorgi had an MRI on Thursday and was diagnosed with a torn capsule in his right shoulder that will sideline him two to three weeks, said Matt Brei, his agent.

With Eli Manning (12 stitches) and Sorgi sidelined, first-year pro Rhett Bomar is going to start and possibly play the entire game when the Giants play the Steelers in a pre-season game Saturday night.

Jets: Coach Rex Ryan smoothed things over with Tony Dungy after the former NFL coach criticized Ryan's use of profanity during HBO's Hard Knocks series. "I wanted him to know how I felt," Ryan said Thursday. "We talked man-to-man. He told me his position and I definitely told him my position. So, it was good."

Packers: Safety Atari Bigby will miss at least four weeks after having ankle surgery earlier this month.

Texans: Linebacker Brian Cushing had his four-game suspension for taking a performance-enhancing drug upheld by the NFL on Thursday.
