Art Schlichter, suspended Baltimore Colts quarterback, apparently will attend classes at Ohio University's Chillicothe branch and play basketball there, the Associated Press reported yesterday.

Ohio-Chillicothe Coach Corky Miller said Schlichter would be a welcome addition to the basketball team, with whom he practiced Friday. According to the AP, Schlichter, who played four seasons at Ohio State, is 70 hours short of a degree.

"First, we have to touch all the bases with everything (before it's all official)," Miller said. "He's very much interested in the school. He just wants to stay in shape. It's very constructive for him; it's like a way for him to occupy his time and at the same time do something he enjoys--play basketball."

Sports at state regional campuses are governed by neither the National Collegiate Athletic Association nor the National Association of Intercollegiate Athletics, Miller said. The school belongs to the Ohio Regional Campus Conference, which has its own rules.

"Everything is set within our own system," Miller said. "He's allowed to play one year of basketball outside of the pros."

Schlichter couldn't be reached yesterday for comment. His family, in Bloomingburg, Ohio, said he had gone to Columbus for the day. Schlichter refused comment Friday.

Schlichter was suspended indefinitely in May by National Football League Commissioner Pete Rozelle after admitting he gambled on football games . . .

San Diego State University's basketball program may be placed on a year's probation for alleged recruiting violations, the San Diego Union reported. An anonymous source in the SDSU athletic department told the newspaper that the NCAA would ban the Aztecs from postseason play this season. The team also would not be allowed to appear on television and would not be allowed to offer any new scholarships for a year following the 1984-85 season.

Being barred from the NCAA tournament this season would be a disappointment to SDSU because it expects to have one of its best teams in recent years.

The proposed suspension stems from allegations that a former basketball player, David Bradley, was given credit for two community college courses he never took. The recruitment of centers Leonard Allen and Michael Kennedy also came under scrutiny.

The Aztecs have reportedly been granted a rehearing on the charges by the NCAA so they can present new evidence . . .

In Kansas City, Mo., five former members of the University of Kansas football coaching staff and two athletes appeared Friday before the NCAA Committee on Infractions, which is investigating alleged recruiting violations by the school.

Former assistant coach John Hadl, three other assistant football coaches, former head coach Don Fambrough, current Kansas running back Kerwin Bell and basketball guard Tad Boyle made appearances before the six-member board.

The committee, which will conclude its meeting today, will not announce its findings until it reviews the allegations and responses.

Nebraska running back Jeff Smith and senior Kansas State running back Iosefatu Faraimo have charged that Hadl offered them as much as $30,000 each to accept athletic scholarships to KU.

Faraimo said Hadl also offered him free clothes and free trips from his home in Vista, Calif., to the KU campus in Lawrence, Kan.

Hadl has denied the allegations.
