The team has honored deceased members of the Celtics family with a commemorative black band on the left shoulder strap of the jersey. It has been featured ten times to date: Walter Brown (1964–65), Bob Schmertz (1975–76), Joan Cohen (1989–90), Johnny Most and Reggie Lewis (1993–94), Dorothy Auerbach (2000–01), Dennis Johnson (2006–07), Jim Loscutoff (2015–16), Jo Jo White (2017–18), John Havlicek (2018–19), Tom Heinsohn, and K. C. Jones (both 2020–21). During the 2019–20 season, the Celtics wore a black band in honor of two people who had never been part of the Celtics organization; former NBA commissioner David Stern and former Los Angeles Lakers star Kobe Bryant. The Celtics have also worn a black band for reasons not directly related to the franchise, such as the Boston Marathon bombing in 2013, and the death of Isaiah Thomas' younger sister during the 2017 NBA playoffs.
