EDEN PRAIRIE, Minn. — Percy Harvin experienced the scariest episode yet in a career plagued by migraine headaches when he collapsed at 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 the second-year receiver. "Percy appreciates everyone's concern," Childress said in a statement posted on the team website Thursday night. "He is alert and resting comfortably, but will remain in the hospital overnight."
The former Gator, who has had migraines since he was 10, returned to the field Monday after missing more than two weeks because of his grandmother's death and migraines. Childress said Thursday's episode was triggered when Harvin looked into a mostly cloudy sky to field a punt during a special teams drill.
Harvin went inside to see the team physician, then went back to the field. Soon after, he was 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'm putting (Harvin's problem) in a migraine category just because of what preceded that," Childress said after practice. "But I certainly don't know what put him down on the ground over there."
Migraine triggers vary from person to person. Rising humidity and changes in barometric pressure can cause the headaches, as can the sun's glare.
The Vikings continued with practice for about five minutes. Then drills were stopped. After Harvin was loaded into the ambulance, the team gathered on the field and took a knee in prayer. The Vikings resumed practice for 10 more plays at the suggestion of quarterback Brett Favre. According to Childress, Favre said, "Let's get one period in here, let's do something,' as opposed to going (inside)."
Practice then ended more than an hour early.
Running back Adrian Peterson, a close friend of Harvin's, visited him in the hospital. "I feel like … he's going to perform very well (this season)," Peterson said.
Harvin also was hospitalized for migraines during his sophomore season at Florida. He missed two games.
Broncos: Starting quarterback Kyle Orton signed a one-year, $9 million contract extension good through 2011, ESPN reported. … Tim Tebow missed his second straight day of practice because of bruised ribs sustained Sunday vs. the Bengals. Coach Josh McDaniels didn't say whether the rookie quarterback from Florida is in or out for Saturday's home preseason opener against the Lions.

Redskins: Defensive lineman Albert Haynesworth missed practice for the second straight day. "More of a headache than anything else," coach Mike Shanahan said.
Texans: The league upheld linebacker Brian Cushing's four-game suspension for taking a performance-enhancing drug. The 2009 Associated Press defensive rookie of the year was suspended in May for testing positive for HCG, a fertility drug on the league's banned substances list.
