McNeil was booked on probable cause Monday afternoon, according to Hennepin County jail records. He was still being held without bail Tuesday morning, when the university announced the decision to suspend him.
According to a police report, the female told Minneapolis police that McNeil, who is her boyfriend, physically assaulted her after a verbal argument. She was taken to a hospital by ambulance for treatment, and McNeil was later taken into custody by University of Minnesota Police.
"Men's basketball student-athlete Daquein McNeil has been suspended from all team activities pending an investigation into a possible domestic assault," athletic director Norwood Teague said in a statement released by the university. "We are currently gathering information and cooperating with the authorities. This athletics department values respect and positively impacting the lives of others and will not tolerate any form of domestic assault from its staff or student-athletes."
McNeil, a sophomore, is averaging 3.3 points, 3.3 rebounds and 2.5 assists for the Gophers, who will face St. John's on Wednesday in the NIT Season Tip-Off at Madison Square Garden.
