With Mike Conley sporting a face mask in his first game back from a facial fracture that required a metal plate to be put into his face, he fell on a play inside. He grabbed the ball and called timeout. At the same time, or immediately after (depending on your perception and fan allegiance), Draymond Green came over the top to grab the ball, hitting Conley in the face. Ow. 

Ow. Ow. Ow. Warriors fans of course felt it was an incidental play, which is how it was called on the floor. It'll be interesting to see if there's any fallout after that play, though, as Memphis clearly felt it wasn't incidental as he reached for his face after the timeout was called.
