On this day in Boston Celtics history, the team would lose several players to the expansion draft held in 1963 to populate two new teams being added to the league.
Expansion drafts function similarly to the regular draft, except the team or teams joining the league can raid the rosters of existing teams for players save for a certain number of “protected” players each team can prevent from being drafted away to the expansion team or teams.
The new teams in question would be the San Diego Rockets and Seattle Supersonics, the former now relocated in Houston, Texas as the Houston Rockets since relocating to Texas in 1971, and the latter now the Oklahoma City Thunder since moving to that state in 2008. Boston would lose three players in total to the two expansion teams.
