The Boston Celtics have released a four-game preseason schedule as the club prepares for the 2025-26 NBA campaign. The team will open exhibition play on Oct. 8 against the Memphis Grizzlies at FedExForum, followed by a road contest versus the Toronto Raptors on Oct. 10. Boston then returns to TD Garden for two home games: Oct. 12 against the Cleveland Cavaliers and Oct. 15 in a rematch with the Raptors. All four contests will be broadcast on NBC Sports Boston. The announcement positions the Celtics roughly a week and a half ahead of the anticipated regular-season tip-off, which league calendars indicate will fall on Oct. 21–22.
