The Southwestern Athletic Conference has reprimanded both the Grambling State and Prairie View marching bands for playing after an offensive team broke its huddle and headed toward the line of scrimmage.
A news release says both the referee and the public address announcer at the Cotton Bowl in Dallas asked both bands to stop playing at those times.
It says a second violation by either band would mean a one-game suspension for that band, and a third would keep them off the field and out of the stands for the rest of the season.
Prairie View beat Grambling State 35-32.
