How to watch Celtics' banner raising, ring ceremony on Opening Night

The TD Garden rafters will get even more crowded Tuesday night.

The Boston Celtics play the first game of the 2024-25 NBA season against the New York Knicks on Tuesday night, and as is tradition, the reigning champions will raise a "2024 World Champions" banner to the rafters in a special pregame ceremony.

The Celtics also will receive their championship rings to honor their 18th NBA title, which surpassed the Los Angeles Lakers for the most in league history.

Boston's 2023-24 campaign was historic in many ways, as the club set multiple NBA records while steamrolling to a 64-18 regular-season record (fourth-best in team history) and 16-3 postseason record that culminated in a five-game NBA Finals victory over the Dallas Mavericks to secure Banner 18.

On Tuesday night, the Celtics' historic achievement will be immortalized in a ceremony that begins at 7 p.m. ET ahead of the game's 7:30 p.m. ET tip-off.

"I feel like it's becoming real, now that we're getting to do this," Celtics big man Al Horford said Monday ahead of Opening Night. "Just very grateful for the position that I'm in."
