(Boston, MA)  --  The NBA is cancelling the Celtics' game tonight following the Boston Marathon explosions.  The team was slated to host the Indiana Pacers at TD Garden, but the league says the game has been called off and will not be made up.  The Boston Bruins also had their Monday night game against Ottawa postponed.  That game will be made up at a later date.
