The Bulldogs are playing without junior guard Makai Mason, who missed the entire 2016-17 season with a broken right foot. Mason, the team's point guard and an Ivy League preseason player of the year candidate, suffered a stress fracture to the same foot, but the problem is not related to the previous injury. An NBC Sports report said Mason could be out at least two months.
Miye Oni scored nine points Sunday and is expected to handle a majority of duties at the point in Mason's absence.
