CARSON, Calif. — Colt Brennan will undergo surgery Monday to repair what he describes as a "slight" labrum tear in his right hip. It is a soft-tissue injury and not cartilage damage.

The rehabilitation period is between eight and 12 weeks, after which he will be fully healed and will not need additional medical procedures for the injury.

"Right now, I'm not 100 percent," Brennan said. "What I will be in July is 100 percent.'

He said he considers the injury to be "minor" and it would not be an issue if he were already on an NFL team. He said health concerns are heightened in regards to draft prospects. He also noted that Priest Holmes had a record-setting season after undergoing a similar procedure.

Brennan said he suffered the injury during a Senior Bowl practice in January. He said it led to what he termed as a "dead leg" effect in his right thigh.

The injury did not prevent him from working out at the NFL Scouting Combine in February nor from competing in today's Pro Day in Carson.

Brennan said he was only told recently that he would require surgery. His agent, Bruce Tollner, said there was some debate whether to release the information. But it was Brennan who insisted on notifying National Football League officials. The 50 or so scouts attending Pro Day were told of Brennan's condition right before the weigh-in session. Each received a letter detailing the chronology of Brennan's injury and treatment.

"I didn't want to hide anything," Brennan said. "I wanted to be honest."

Under the direction of San Francisco 49er quarterback coach Ted Tollner, Brennan threw for about an hour today. He did not participate in the running or weightlifting drills.

Brennan was accurate on passes of all ranges, Tollner said.

"There's no question he can play at the next level," Tollner said. "He can make all of the throws."
