Zeigler has been suspended indefinitely by head coach Jamie Dixon.
"The incident involving Trey Zeigler is not only surprising, but incredibly disappointing," Dixon said in a statement. "Although I believe it was out of character for Trey, he has been immediately suspended until further notice. Trey has expressed his deep regret to me and understands and respects the importance of accountability for one's actions."
"I want to apologize to my family, the University of Pittsburgh, my teammates and coaches and the entire Pittsburgh community," Zeigler said. "This is not indicative of the kind of person I am, nor the kind of person I want to be."
