The NBA Eastern Conference second round series between the Celtics and Philadelphia 76ers shifts back to Boston for game five tonight.
The Celtics lost a heartbreaker in overtime on Sunday to even the best of seven series at two games apiece.
Boston head coach Joe Mazzulla took some of the blame for the game four loss, saying he should have called a timeout during the final possession of overtime.
Mazzulla says he didn't want the Sixers to substitute, but not calling time may have cost his team an extra shot at a winning basket.
