Stephen Curry walked with a noticeable limp leaving the arena, and Kerr said the team would know more about the extent of the injury Thursday. Golden State players and Kerr stopped short of rebuking Horford, but fans on social media already were labeling it a “dirty play.” Celtics defensive specialist Marcus Smart defended his teammate from the social media reaction. “It’s the Finals. You’ve got guys diving all over the place. Their guys are diving into us. We don’t say nothing,” Smart told Yahoo Sports. “We’re getting hurt as well, but we continue to play. Nothing is intentional. It’s the Finals. We’re trying to win just like them. First one to the ball, as we all know, wins. They can complain all they want. It is what it is. There’s nothing dirty about it. It’s fair game. It’s fair basketball. It’s Finals basketball. … Nobody is out here trying to hurt anybody.”
