Dallas Mavericks owner Mark Cuban said on Thursday he hopes the National Basketball Association will allow players to take a knee during the national anthem to support protests over the May 25 death of George Floyd in police custody.

Video footage showed a white police officer in Minneapolis kneeling on Floyd's neck for nearly nine minutes before the unarmed 46-year-old African American man died, triggering outrage and protests across the United States and in other countries.

NBA rules require players and coaches to stand during the national anthem, but Cuban told ESPN the league can soften its stance and give players the freedom to express themselves in a respectful manner.
