The ACC/Big Ten Challenge highlights Tuesday night for basketball fans nationally, but Harvard's Tuesday night game against Vermont is also televised on a night when the Boston Celtics are off.

College basketball: Vermont Catamounts vs. Harvard Crimson, 7 p.m., NBC Sports Network: Replacing Kyle Casey and Brandyn Curry might prove to be as hard as the defending Ivy League champions expected: although freshman Siyani Chambers has impressed with 9.8 points and 4.8 assists as the team's point guard, they've lost two of three against D-I competition, a loss at the buzzer against UMass and a blowout loss to St. Joseph's. Vermont, on the other hand, is 3-1 with their only loss to then-No. 23 UConn, coming off double-digit wins over Boston-area squad Northeastern and fellow Ivy League team Yale.
