NBA commissioner Adam Silver, however, doesn't expect to see any players kneeling during the national anthem before games.
"My expectation is that our players will continue to stand for the anthem," Commissioner Adam Silver said, citing long-standing league rule.— Scott Cacciola (@ScottCacciola) September 28, 2017
Unlike the NFL, the NBA has a rule that expressly prohibits kneeling during the playing of the national anthem:
Players, coaches, and trainers must be present, stand, and line up in a dignified posture along the foul lines during the playing of the American and/or Canadian national anthems.
The rule was tested by then-Denver Nuggets guard Mahmoud Abdul-Rauf in 1996, when he made the decision to sit during the playing of "The Star-Spangled Banner." The NBA suspended Abdul-Rauf for one game, and when he returned he stood for the anthem, but closed his eyes and prayed silently into his hands.
The issue of anthem protesting is one that continues to rage during the NFL season, and it will surely come up again when NBA preseason games begin on Saturday.
