Trainer: More than migraine caused Percy Harvin to pass out

SAN FRANCISCO -- It wasn't just a migraine that made Percy Harvin collapse on Thursday.

Eric Sugarman, the Minnesota Vikings' head athletic trainer, told NBC that Harvin passed out because of several other factors, possibly including dehydration, low blood pressure and adverse reaction to medication team doctors gave the playmaking receiver after he suffered a migraine earlier in the day.

Sugarman -- who generally is not made available to reporters -- also provided a detailed account of the incident and said Harvin had not gone off or changed his medication during his two-week absence from the team during training camp.

Harvin rejoined the team on Friday and watched the beginning of practice. He visited more specialists this weekend, Sugarman said, and four trainers were left in the Twin Cities while the team traveled to San Francisco -- a game in which Harvin, at least from a medical perspective, could have played.

The second-year receiver will undergo more tests this week and likely will be on medication for life, according to Sugarman, who said the key is attacking the migraine the moment Harvin has a symptom.

"This is going to be a lifelong fight," Sugarman said.
