This is the practice where Blake Griffin injured his knee. An injury that required him to leave Team USA and head back to Los Angeles for an MRI and to be looked at by Clippers team doctors.
You can’t tell a lot from the video, particularly the second play, the view is obscured. It was just a fluke thing on a landing after an “I’m not just surrendering the dunk” foul.
Hat tip to the fantastic international hoops site Sportando for finding this video.
