Siegel boys basketball coach Ben Dotson announced his resigned on Tuesday, just six days after his team's last game of the season.
He plans to stay at the school as a teacher.
Dotson, through the team's basketball website, said he desires more time to be with his daughter and wife. He became a father last year.
Principal Larry Creasy will begin a search for his replacement. Jon Palmer, the son of longtime MTSU play-by-play announcer Dick Palmer, has been on staff for many years. Also, former Oakland head coach Mike Wright was hired as an assistant this year.
