Dallas Mavericks guard Kyrie Irving arrived at Game 2 of the NBA Finals on Sunday night holding in his hand a keffiyeh, a traditional headscarf worn by Palestinians that has become known as a symbol of solidarity with the Palestinian cause and opposition to Israel.

The NBA star, 32, was videotaped holding a backpack that had the keffieyh tied to it. The Boston Celtics eventually beat the Dallas Mavericks that night 105-98.

Irving has carried keffiyehs in the past and expressed support for Palestinians amid the ongoing Israel-Hamas war.

In November, the athlete wore a black and white keffiyeh draped on his head during an NBA press conference, and at a recent press conference he sported a necklace in the shape of Israel that was covered by the Palestinian flag.
