A college track-and-field coach, who formerly worked at The University of Texas at Austin, is a defendant in a new putative class action lawsuit that alleges the National Collegiate Athletic Association harmed student-athletes by permitting coaches’ sexual contact with them.

Three former student-athletes have sued coach John Rembao, the NCAA and its board of governors. But they’re looking to broaden their lawsuit into a class action with NCAA student-athletes—male and female—spanning back to 1992. Their proposed class would be large, considering the NCAA has 460,000 student-athletes competing in 24 sports every year, according to its website.
