Longtime West Texas A&M Football Coach Don Carthel was dismissed Thursday due to what the school called a "major" NCAA rules violation.
Assistant coach Mike Nesbitt will assume his duties, effective immediately.
Athletic Director Michael McBroom said in a news conference that the reason for Carthel's dismissal was,
"A violation of NCAA bylaw 10.1, governing ethical conduct. Specifically, knowingly furnishing or knowingly influencing others to provide false or misleading information in the course of an NCAA investigation."
McBroom said there was a single incident this summer which came to his attention in the past 24 hours, leaving him no choice but to dismiss the coach.
Carthel is the winningest coach in West Texas A&M football history, finishing 79-22 in eight seasons leading the Buffaloes.
His WT team was the overwhelming pre-season pick to win the Lone Star Conference and is ranked #3 nationally in the pre-season AFCA Division II Coaches' Poll.
