Sean Grande and Cedric Maxwell call Celtics games on the 98.5 The Sports Hub radio network. The station's guide lists ROCK 92.9 as the home for select broadcasts when scheduling conflicts arise.

If the game is not on the flagship, check that alternate before assuming the broadcast is unavailable. The Celtics Radio Network page also lists affiliates for listeners outside Boston. Check the current listing before tipoff, especially on nights with other Boston teams in action.
