A former NBA player found himself in the middle of some controversy for his actions last week with his Chinese Basketball Association team.

Guerschon Yabusele was fined $1,400 for failing to look at the Chinese flag while the Chinese national anthem blared before Friday’s game. The Nanjing Tongxi Monkey King forward also was given a “serious warning” over his actions, the Chinese Basketball Association said in a statement.

Chinese Basketball Association players are required to stare at the Chinese flag while the “March of Volunteers” plays. Video from the game appeared to show Yabusele with his head down during the anthem.

“I have the same routine, I've been doing this my whole career and I wanted to apologize for the people that took it Personnal [sic] because it was not my point,” Yabusele said, according to TMZ Sports. “I will show my respect during the Chinese national anthem and keep my head up for now on, Love you guys.”
