The NCAA accused Texas Tech of major rules violations tied to recruiting on Friday, saying 16 athletics department staff members sent nearly 1,000 impermissible text messages sent to football, softball and golf prospects. The NCAA said the school discovered the violations and reported them. It did not add punishments beyond the school's self-imposed two years of probation, recruiting restrictions and scholarship reductions. The NCAA said the football violations occurred between August 2007 and February 2009, which would have come under former coach Mike Leach. The NCAA said the football coaching staff sent approximately 234 text messages to 45 prospective student-athletes. Leach, who was fired in December 2009 amid allegations he had mistreated a player with a concussion, told the Finebaum Radio Network no one on his staff broke any rules. "I don't know anything about it," said Leach, who has sued the school over his termination. "We never had anything more than a secondary violation when I was there." Tommy Tuberville, who just completed his first year as Tech's football coach, said every coach and staff member understands NCAA and Big 12 Conference rules.
