A crackdown on student behavior at football games will be in effect this weekend in response to injuries suffered from thrown water bottles and complaints from fans.

University spokesman Bill Mahon said anyone caught throwing objects will be ejected from the game, subject to arrest and referred to the Office of Judicial Affairs. He added that anyone found guilty of throwing objects will be barred from attending future home games for as long as they are students at Penn State.

"You'll be spending the rest of your college career watching games on TV, assuming you haven't injured someone and you're sitting in jail," Mahon said.

While acknowledging that keeping offenders out of games might be a difficult policy to enforce, he said those caught doing so risk getting kicked out of school.

"Sorry we have to remind you, but it's against the law to hit people, and there are consequences for your actions," Mahon said.

If a fan is caught injuring another, "The least worry [he or she is] going to have is getting into a football game," he added.

Thirty-five students were ejected from last week's game, and Mahon said security will be increased in the student section of Beaver Stadium, which has received the most complaints.

Rubina Javeri, Undergraduate Student Government president, said she doesn't condone the recent behavior of some of the student fans, but is disappointed that the student body wasn't consulted before decisions on disciplinary actions were made.

"I hope that discussions between students, university administration, athletics and alumni can work together to create an appropriate policy," Javeri said.

Two students sought treatment for injuries after being hit by water bottles at last week's Louisiana Tech game. One was treated at the scene for lacerations to the scalp, and the other was treated Sunday for a fracture to the orbital bone around the eye, Penn State Police Supervisor Clifford Lutz said.

The eye injury came "within millimeters" of causing sight loss to the victim, said David Lindstrom, associate director of administration for University Health Services. He added that two years ago a person suffered temporary loss of sight in a similar incident.

In addition to the students, a 60-year-old woman with brittle-bone disease was treated when she was struck in the back by a water bottle.

"It's unfortunate people celebrate in a way that causes injury to others," Lindstrom said.

Erin Flaherty (freshman-division of undergraduate studies) said she suffered a slight concussion after she was hit in her left temple by a full bottle of water at last week's game.

"I still have a lump on my head," Flaherty said.

Mahon said that, in addition to the injuries, the university has been inundated with e-mails from fans and concerned parents complaining about the recent bottle throwing. One parent said her daughter was hit in the head twice at a recent game.
