TCU coach Gary Patterson says starting quarterback Casey Pachall will not face team discipline after the junior admitted to police in February that he used marijuana and failed a drug test in February.
Pachall gave a statement to reporters at the start of a press conference and apologized for his actions.
TCU players were scheduled to report Sunday for the start of fall practice.
Pachall was interviewed by Fort Worth police when his former roommate, linebacker Tanner Brock, and three other TCU football players were among the students arrested Feb. 15 after a six-month drug sting.
Pachall threw for a school record 2,921 passing yards last season.
McPherson's Tyler Matthews is competing for a job at quarterback as a freshman at TCU.
