On this day in Boston Celtics history, the NBA would cancel a game between the Boston Celtics and the Indiana Pacers a day after the Boston Marathon terrorist attacks that occurred in 2013. The move was made out of respect for the victims of the bombing after an initial postponement, and the game was ultimately not rescheduled.
The cancellations did not impact the postseason, as seeds that could have otherwise been impacted were already locked into their position, marking the most recent season the NBA has had an odd number of regular-season games as a result, with 1,229 games played.
