Boston Celtics release full 2026-27 preseason schedule

BOSTON — NBA Summer League has wrapped up, and that means the Boston Celtics won't play again for months. However, the Celtics officially announced when that basketball drought will end, as they released their 2026-27 preseason schedule on Monday morning.

On Thursday, October 8, the wait will be over. The Celtics square off against the Cleveland Cavaliers on the road for their first preseason showdown. Two days later, the Celtics face the Philadelphia 76ers at TD Garden in what could be a highly-anticipated matchup. Boston traded star guard Jaylen Brown to the rival Sixers this offseason and Saturday, October 10, might mark his first time playing against his former team. However, it's worth noting that stars usually sit for multiple preseason contests, especially ones who've been in the league for over a decade.
