Assistant Texas Attorney General John Vasquez said yesterday he has evidence a former Southern Methodist University athletic department employe may have stolen at least $10,000 from the department in the pay-for-play football scandal.

Vasquez suggested others may be involved in what he called the theft or misapplication of funds, but would not elaborate.

He presented his findings yesterday to the SMU board and SMU President A. Kenneth Pye, who pledged assistance in the investigation.

Vasquez said he expected to gather enough information to present a case to the Dallas County district attorney within two weeks. He would not specify the amount he said was stolen, but said it was at least $10,000.

Payments to football players at SMU led to the NCAA's February decision to ban football at the school this year -- the harshest penalty ever handed to a college football program. The university took the additional step of cancelling its 1988 season . . .

The NCAA will be limited to testing Stanford football and basketball players only for amphetamines, anabolic steroids and cocaine, Santa Clara County (Calif.) Superior Court Judge Conrad Rushing ruled.

Rushing ruled Nov. 19 that the NCAA could not test Stanford athletes in 26 sports. He allowed testing in basketball and football because of evidence of drug use in those sports.

The NCAA also must change its procedures for the postseason tests so that athletes are not required to urinate while being watched by monitors, he said . . .

The NCAA will establish a $9 million scholarship fund for athletes who did not graduate but decided later to return to school, says Dick Schultz, executive director of the NCAA. The NCAA would provide $6 million for the scholarship program this year, with $1 million to be added to the fund each of the next three years, he said.
