"After a complete investigation by our staff, which included a discussion with Coach June Jones earlier today, we believe that a screwdriver was thrown by one of our fans at the University of Hawai'i team bench during Friday night's football game," Johnson said in a statement distributed to Jones, UH officials and the media.

"We sincerely apologize to June Jones, the Warrior football team and the University of Hawai'i for the incident," Johnson added. "I am embarrassed by that type of fan behavior. It tarnishes the 'Red Wave,' which has a great reputation across the nation for it's outstanding support of Bulldog athletics."

The Red Wave is the nickname for Bulldog supporters, who often line the path leading to the field, yelling insults at visiting players.

But after UH's 31-21 victory last Friday, its first in Fresno since 1973, UH players and coaches complained of being the target of thrown objects. Jones said there were beer bottles thrown near the UH bench, and after the game, he found a screwdriver near where he was standing.

"We will not tolerate fans throwing objects onto the the field," Johnson said. "This is a serious issue. Anyone caught throwing anything on the field in the future will be dealt with accordingly, including criminal charges."

When told of the apology after this morning's practice, Jones said, "It's unfortunate one or two drunks do something that affect the whole school."

As a whole, Jones said, Fresno State officials "did a great job with security. They can't control 35,000 people."

Jones said the crowd's behavior was better than the previous time UH played in Fresno, in 2000, and comparable to what a visiting player goes through in the National Football League.

"It's like Cleveland or Philadelphia or New York when you go into those stadiums," Jones said. "It's the same way. Unfortunately, one or two people give 35,000 a bad name."
