Schedule and results
The 2018 Big Ten tournament will be held at Madison Square Garden in New York City. Due to the Big East's use of that venue for their conference tournament, the Big Ten tournament will take place one week earlier than usual, ending the week before Selection Sunday. This could result in teams having nearly two weeks off before the NCAA tournament.
