Bethel, a freshman from Miami, punched Texas Tech women's basketball player Amber Battle in the face during a pickup basketball game.
"Texas Tech Athletics has a zero tolerance policy on this type of behavior," the school announced in a statement.
According to the Lubbock Avalanche-Journal, Battle is expected to have surgery after sustaining a broken bone from the hit. Battle was the Red Raiders' leading scorer with 16.4 points per game last season, and also led the team in rebounds and assists to earn second-team All-Big 12 honors.
Texas Tech spokesperson Blayne Beal confirmed to ESPN.com that Battle was the victim in the incident, but did not know when or if she will require surgery.
Bethel was Texas Tech's highest-rated recruit in its incoming freshman class, an ESPN 300 prospect from Miami's Booker T. Washington High School who joined the program this summer.
He was expected to participate in both football and track at Texas Tech.
