The NCAA, which earlier this week notified the University of Florida football program that it had been found guilty of 59 violations of rules and placed on three years probation, yesterday reprimanded the Gators' men's and women's basketball programs.

Florida released the contents of a confidential letter from David Berst, the NCAA's director of enforcement, under the state's public records law.

The NCAA said its Committee on Infractions had found one violation committed in Coach Norm Sloan's men's basketball program and three in the women's program headed by Coach Debbie Yow.

The NCAA said that during the summer of 1980, Sloan transported two prospective student-athletes from a summer camp that was being conducted on Florida's campus to a local residence where he entertained the prospects at an outdoor barbecue.

In April 1984, the letter said, Yow provided prospective student-athlete Belitta Croley automobile transportation in the Lexington, Ky., area. The NCAA also said Yow contacted Croley on more than three occasions for recruiting purposes at sites other than the recruit's high school, and that Yow participated in a basketball workout with Croley for a short period of time on one occasion.

"In considering these matters, the Committee on Infractions noted that the violations were of an isolated and inadvertant nature and did not appear to exhibit a pattern of improprieties," the NCAA letter said . . .

Texas Christian football Coach Jim Wacker, who turned the Horned Frogs into a winning team this year, has been given a new seven-year contract, university officials announced. The agreement replaces Wacker's original four-year pact, which had two years remaining.

Last year, the Horned Frogs were 1-8-2; they are now 5-1.
