Tests negative on Viloria

MANILA, Philippines -- Hawaiian Brian Viloria was taken to a hospital from apparent exhaustion soon after his TKO defeat by Colombia's Carlos Tamara in Saturday's IBF light flyweight title fight, a boxing official said.

Viloria will have to remain there for at least two days and won't be cleared by doctors to fly home for at least 10 days. He will need to return to the hospital to ensure there is no latent brain swelling, his manager Gary Gittelsohn e-mailed The Associated Press.

All tests came back negative on Viloria, who was knocked out by Colombia's Carlos Tamara in a light flyweight title fight. Referee Bruce McTavish stopped the fight 1:45 into the 12th round.

Soon after the bout ended, Viloria was taken from his locker room and rushed to a local hospital in an ambulance. His camp did not immediately give details of what happened inside the room after the fight.

Neurologist Regina Macalintal said Viloria did not need any surgery and a minor cut to his brow was sutured.

Boxing analyst Ronnie Nathaniels told DZBB radio he spoke at the emergency room with Viloria, who complained of a "severe headache."

The emergency room doctor who attended to Viloria at the first hospital, Dr. Ernesto Gonzales, said Viloria was taken to the first hospital because he "felt weak" but was conscious when he arrived on a stretcher.

"All I can say is he was stable from the time he arrived until he left," Gonzales said.

Asked by reporters how Viloria was doing, his trainer, Robert Garcia, said, "He's fine."

Viloria was in control early in the fight at the Cuneta Astrodome in suburban Pasay city but he slowed down starting in the seventh round and Tamara took control.

Viloria appeared exhausted and received numerous hits to the face toward the final rounds. He suffered a cut above his left eye.

He fell twice after swinging and missing Tamara and had to be helped up by the referee in the final round.

Viloria wasn't returning punches from Tamara as he staggered against the ropes when McTavish stepped in to stop the fight.

"I was confident about this fight," said Tamara, a veteran of the 2004 Olympics. "My team knew this was my chance to become a world champion. Brian is a tough fighter."

Viloria, a former WBC light flyweight champion nicknamed "The Hawaiian Punch," claimed the IBF belt with a knockout of Ulises Solis in the Philippines in April last year, and defended the title with an unanimous decision over Jesus Iribe in Honolulu in August.

This was Tamara's second shot at a major belt after losing a decision to Omar Narvaez for the WBO flyweight title in January 2008.
