The NCAA Committee on Infractions has voted to impose two years probation with sanctions on Clemson University's football program, according to sources. The probation was voted for infractions that include recruiting violations.

The committee voted to take these sanctions against Clemson, college football's defending national champion:

* Bar Clemson from NCAA national and regional television appearances for two years.

* Prohibit the team from playing in a postseason bowl game for two years.

* Reduce the scholarships the school could grant.

It could not be determined whether other sanctions were involved.

Clemson can accept the proposed sanctions or appeal them to the NCAA Council.

The NCAA also has asked Clemson to show cause why the university should not take disciplinary action against three assistant coaches.

According to published reports, the six-member Committee on Infractions, chaired by Charles Alan Wright, a noted expert on constitutional law and a law professor at the University of Texas, made its decision Oct. 31 following three days of hearings in a Chicago suburb.

In Tuesday's editions, The Washington Post reported that the Atlantic Coast Conference's eight faculty representatives, independent of any action that might be taken by the NCAA, had voted to impose a two-year probation on Clemson. That probation includes the university's forfeiting its share of conference television revenue both years.

The ACC action, like the NCAA committee vote, is subject to appeal.

Bill Lee Atchley, Clemson's president, was unavailable for comment yesterday. On Monday night, he said that Clemson had received the ACC report, but not the NCAA's confidential report. He was noncommittal about appeals, saying that Clemson would appeal any decision it considers unfair.

Hale McMenamin, NCAA assistant director of enforcement, declined comment, citing longstanding NCAA policy neither to confirm nor deny any details surrounding an NCAA investigation.

It is the second time since 1975 that the NCAA Committee on Infractions has voted major sanctions against Clemson. In that year, the basketball program was placed on three years probation and the football program publicly reprimanded.

The current NCAA investigation began in January 1981, according to published reports. The NCAA brought more than 150 charges against Clemson, according to a source who has read the charges and Clemson's reply to them. The number and severity of the infractions found by the committee could not be determined. If proposed sanctions are accepted by a member institution or if a member appeals proposed sanctions and loses, it is NCAA policy to release publicly details of the infractions. However, the NCAA does not identify the names of coaches, players or other representatives of the athletic department involved.

Clemson has 15 days from the date it receives the NCAA's confidential report in which to appeal. An appeal would be heard at the next meeting of the NCAA Council during the NCAA convention in January at San Diego.

Clemson (6-1-1), which will play the University of Maryland on Saturday in College Park, now is ranked as high as 10th nationally and is a prime candidate for postseason bowl games.

Bowl sources say that Clemson is in contention to return to the Orange Bowl, where it earned the national championship by defeating Nebraska on New Year's night. Clemson also is in contention for the Liberty Bowl Dec. 29 at Memphis, among others.

If Clemson accepted the proposed penalties after Nov. 20, the day on which bowl contracts officially may be offered, or if the school appeals the decision, then Clemson apparently would be eligible for bowl competition this year, but would be ineligible following the 1983 and 1984 regular seasons.
