The NBA won’t allow players to wear “ninja-style headwear” this season.

Several players including the Miami Heat’s Jimmy Butler, the New Orleans Pelicans’ Jrue Holiday, the LA Clippers’ Montrezl Harrell, the Minnesota Timberwolves’ Karl-Anthony Towns and the Brooklyn Nets’ Jarrett Allen, regularly wore the headgear a season ago.

The NBA never had a formal process to approve the headgear, and allowed players to wear it during the 2018-19 season because, spokesman Mike Bass told ESPN, “We didn’t want to cause a disruption by intervening midseason.”

The NBA notified teams in May that the headbands wouldn’t be a part of this season’s approved uniforms.

The NBA’s competition committee planned to discuss the headwear as part of its meetings in Chicago on Monday, Bass said.
