KNOXVILLE, Tenn. -- The Tennessee Volunteers have reported 18 Level III violations to the NCAA since May, including four in football.

The NCAA defines a Level III violation as a breach of conduct that is "isolated or limited in nature." The violations were first reported by the Knoxville News-Sentinel.

One of the football violations led to defensive backs coach Willie Martinez being suspended for the 2015 season opener due to impermissible off-campus contact with a prospect during a spring evaluation period. Tennessee also got a 10-day reduction of spring 2016 evaluation days, and Martinez had additional limits in his off-campus recruiting.

Tennessee also reported three violations each in women's basketball and swimming, two each in women's rowing and women's golf and one apiece in men's basketball, softball, women's soccer and women's tennis.
