The Boston Celtics officially announced the free agent signings of center Tristan Thompson and point guard Jeff Teague on Monday, and they also revealed jersey numbers for both players.
Handing out jersey numbers is more difficult for the Celtics than any other franchise. The Celtics have won 17 NBA championships in their storied history. So, it's understandable that the team has retired 23 numbers.
Teague will wear No. 55, which was not used last season.
This number most recently was worn by Greg Monroe during the 2018-19 season. It has been worn by 11 players in team history, including Jordan Mickey, E'Twaun Moore, Luke Harangody, Wally Szczerbiak and Eric Williams, among others.
Thompson will wear No. 13 -- most recently worn by Marcus Morris from 2017-18 through 2018-19. It also was not used last season.
This number has been worn by 19 players in Boston, including James Young, Shelden Williams, Gabe Pruitt, Delonte West, Dana Barros, Todd Day, Charles Smith and several others. No. 13 was first worn by Red Wallace in 1947.
