STATE COLLEGE, Pa. - Penn State running back Austin Scott did not dress for yesterday's game against Iowa because of an unspecified violation of team rules.

"His status is very much in doubt as far as playing, period," coach Joe Paterno said.

Paterno would not confirm whether Scott had been kicked off the team. According to a team source, his locker had been cleaned out.

"I don't want to tell you what to speculate, because I might be speculating myself," Paterno said. "I don't think it's fair for me to get into anything right now."

According to Jeff Nelson, assistant athletic director for communications, Scott still was enrolled at Penn State. The player was at home yesterday in Allentown with his family.

Calls placed to Scott's campus apartment yesterday morning were not answered.

Penn State police confirmed yesterday that a female student told authorities she had been sexually assaulted early Friday on campus.

"The victim knew the suspect," assistant chief of police Tyrone Parham said.

WJAC-6 Johnstown, an NBC affiliate, reported that the woman told police she had been assaulted by a football player who starts on offense. No charges have been filed.

Nelson said that Penn State has no knowledge of a sexual assault involving one of its football players.

The team was told of Scott's status Friday evening.

"Everyone knows that you've got to watch yourself wherever you go," linebacker Dan Connor said. "As far as [Scott's] situation, I don't know any details. You've got to be careful. You've got to keep your nose clean."

A fifth-year senior, Scott lost his starter's spot to Rodney Kinlaw last week against Illinois after fumbling four times in the previous three games. He played later in the game, and has 320 yards rushing and six touchdowns on 69 carries this season.

With Scott unavailable to play, redshirt freshman Evan Royster moved up behind Kinlaw on the depth chart.

In the Lions' 27-7 win over Iowa, Kinlaw ran for 168 yards and two touchdowns on 28 carries. Royster finished with 88 yards on 16 carries.

A product of Parkland High in Allentown, Scott is Pennsylvania's all-time leading rusher. Often in Paterno's doghouse for minor infractions, Scott has never been the No. 1 tailback the program and Lions fans had envisioned.

Scott sat out last year as a redshirt with a minor ankle injury. He was sent home from the Outback Bowl in Tampa., Fla., in December for what the team called "personal reasons."

Other legal matters. The Centre County district attorney's office said Friday that it will not file additional charges in the April off-campus fight involving several Penn State players.

District Attorney Michael Madeira told reporters that his office found nothing new or different from the evidence State College police already had provided.

Charges against Jermone Hayes, Lydell Sargeant, Tyrell Sales and Justin King had been dropped.

Anthony Scirrotto of West Deptford, N.J., and Chris Baker of Windsor, Conn., will stand trial on several charges, including trespass and assault.

Freshman running back Joe Suhey was cited for underage drinking Friday night, Penn State University police said. He is the son of former Penn State fullback Matt Suhey.
