MELBOURNE, Fla. (AP) _ Penn State has told the NCAA it is investigating the report that All-American running back Curtis Enis improperly received a gift from an agent.

Enis, meanwhile, took part in workouts as the Nittany Lions prepared for the Citrus Bowl.

John Bove, compliance director for Penn State, is conducting the inquiry out of State College, Pa., sports information director Jeff Nelson said Monday. Nelson could not say when the investigation would be completed.

``(There's) no timetable,'' Nelson said. ``We want to be as thorough as we can while also gathering the information and come to some sort of determination.

``We're talking to as many people as we can, finding out as much information as we can.''

WHTM-TV in Harrisburg. Pa., reported Friday that Houston-based agent Jeff Nalley bought Enis $400 in clothing on Dec. 6 in a Harrisburg-area mall.

Enis denied the charge and said his girlfriend bought the suit he wore to ESPN's Doak Walker Award ceremony on Dec. 11. Nalley backed him up, saying he purchased a $75 shirt and $325 suit at John Craig Fashions in Camp Hill for former client Lovell Pinkney, a tight end released by the Green Bay Packers in August.

On Monday, the television station reported that several Harrisburg mall employees said they were certain they had seen Enis on Dec. 6. None of the workers would appear on camera.

Enis was not available for comment Monday because practice was closed to the public, as usual. This season he led the No. 11 Nittany Lions in rushing with 1,363 yards and was the team's most consistent offensive player. He's third all-time at Penn State with 3,256 yards.
