Athletes in various sports took a knee over the weekend as an act of silent protest against racial inequality.
Australian Nick Kyrgios did the same before his match against Roger Federer at the Laver Cup in Prague.
Most assumed he did so in solidarity. But Kyrgios said it was a personal gesture.
“I’m doing that before most matches just to remember, you know, the two most important people that have passed away,” Kyrgios said afterwards.
