Meyers Leonard of the Miami Heat chose to stand for the national anthem while the rest his teammates knelt on Saturday, during the team’s reopening game against the Denver Nuggets at Walt Disney World.

Despite his public support for the Black Lives Matter movement, he says he couldn’t bring himself to kneel in protest.

“I absolutely believe Black Lives Matter,” he said, according to the NBA.

Nevertheless, he stood with his hand over his heart as “The Star-Spangled Banner” played just before tipoff.

On Twitter, the sister of Al Horford, Anna, jumped all over the opportunity to blast him for his actions.
