The NBA issued Raptors guard Kyle Lowry a warning for flopping on Thursday.

Lowry’s flop occurred in the second quarter of Toronto’s 125-114 home victory over Philadelphia on April 9. With a little under six minutes remaining before halftime and Toronto leading 50-45, Lowry fell backwards to the court while attempting to take a charge.

Elliot Williams pushed the ball up in transition and Lowry prepared himself for contact outside the protected circle. Instead of being run down, though, Lowry slowly drifted backwards to the court because the collision never took place. Williams was able to twist his way around Lowry before laying off a pass to Thaddeus Young. No foul was called on the play.
