Clemson coach Larry Shyatt resigned Monday night, Shyatt told ESPN.com.

A source said Shyatt was pressured to resign.

Shyatt was 15-13 overall this season, but wasn't invited to the NIT out of the ACC. The snub shocked the Clemson staff. The Tigers were 5-11 in the ACC and beat Cincinnati and swept Virginia. Shyatt was an assistant at Clemson for three years before going to Wyoming, where he was head coach for five years.

Shyatt had two seasons left on his contract. Shyatt went to the NIT title game in his first season.

"Love the program and fought back hard but it wasn't enough wins yet,'' Shyatt said. "We changed the culture and socially and academically that was unacceptable and I'm proud of the group. All five seniors will graduate in school history. We have no regrets but leaving behind some awfully young men.''

Shyatt will become an immediate candidate for the vacant Cleveland State opening. His wife's family is from the Cleveland area.

Clemson loses its best player in Ed Scott, who was a senior.

Candidates to replace Shyatt will likely be Western Kentucky coach Dennis Felton, Dayton coach Oliver Purnell, former Hawks coach Lon Kruger and former Bulls coach Tim Floyd. Chattanooga coach Jeff Lebo could also be a candidate.
