Kyrie Irving got a flagrant 1 for throwing a small punch at Paul Pierce's side in the fourth quarter of the Cavaliers' loss to the Clippers on Thursday night.

It looks like Irving may have been reacting to getting hit by Pierce (though I'm sure the Cavaliers being down by 20 also played a part). Pierce leans forward a bit as Irving runs into him.

This was the Cavs' fourth loss of the season. Irving finished with a game-high 28 points.
