Brennan suffered the injury when he was walloped by Fresno State linebacker Marcus Riley in the fourth quarter of UH's 37-30 victory at Aloha Stadium. UH is 9-0.

Brennan said the decision to play rests with head coach June Jones and the medical staff.

As a precaution, Brennan will be held out or practices tomorrow and Tuesday, Jones said. Brennan said he will be evaluated Tuesday night.

In following a UH policy, a player who suffers a concussion is monitored for 48 hours.

Brennan, who was told he does not need a CAT scan, said he does not have any headaches, but is experiencing some body pain.

He said Jones will determine whether he plays on Friday.

"It's in his hands," Brennan said.

Brennan said he was told a short rest time increases the likelihood of suffering a second concussion.

"He's looking out for my health," Brennan said. "He wants to make sure the best decision will be made Friday."

He also said he suffered the injury on a "good hit," and does not harbor any ill will toward Riley.

"I don't think there was anyhing cheap about it," said Brennan, who saw the television replay of the hit.

Jones and Dennis McKnight said Brennan was knocked unconscious for a few seconds.

Brennan declined to comment on whether that was the case.

Brennan suffered the injury while he was scrambling on a third-and-7 play and was knocked out of the game with 10:43 left.

The near-sellout crowd drew silent and teammates prayed on one knee as the game was halted for about five minutes. Brennan stood up, wincing in pain and was helped off the field into the locker room.

After being escorted to the medical training room, Brennan was groggy for a while. But he did not experience nausea, one of the side effects of a concussion. He had a minor neck ache. He was given a foam neck wrap to allow him to sleep peacefully.

Brennan was not available to the media after the game, but said in a statement that he was "looking forward to getting back on the field for next week's game."

Reports circulated throughout the media and TV stations reported that Brennan had suffered a Grade 3 concussion, the most severe of all levels and one that would sideline an athlete for an extended period.

However, that report was never issued by UH, which said after the game that Brennan had suffered a "mild" concussion and his condition was "day-to-day."

According to UH officials who observed Brennan in the locker room after the game, the quarterback was talking, engaging in conversation and even joking.

"He showed a lot of heart by getting to his feet because we all knew he was out of it," Warriors receiver Ryan Grice-Mullins said.

Grice-Mullins said it was a helmet-to-helmet hit, but not dirty. He admitted it was difficult to concentrate on the game because he was so concerned about his quarterback.
