Southern Methodist University, its 1987 and 1988 football seasons canceled because of illegal payments to players, is being investigated by the NCAA for possible rules violations in its basketball and track programs and could face the so-called "death penalty" in those sports, the Dallas Times Herald reported.

NCAA enforcement director David Berst said if violations are found to have occurred after the university was placed on probation in August 1985 for football recruiting infractions, the programs involved would be subject to the same penalty the football program suffered: the suspension of that sport at SMU.

SMU Athletic director Doug Single confirmed that the NCAA is looking at information a private investigator uncovered during a seven-month study . . .

Glyn Milburn, a 5-foot-9, 165-pound football whiz who set the state single-season rushing record with 2,718 yards at California's Santa Monica High last fall, signed with Stanford last Wednesday -- but evidently will be attending Oklahoma.

Milburn, according to the Los Angeles Times, has signed a national letter of intent to attend Oklahoma, after the Stanford assistant coach who took his school's letter to Santa Monica left it to Milburn to take to his parents for the required additional signature -- and, the newspaper said, neither parent signed.
