On Saturday night, Boston Celtics fiery guard Marcus Smart got into it with Atlanta Hawks third-year swingman DeAndre' Bembry. The on-court altercation led to Smart's ejection, which appeared to give Cleveland Cavaliers veteran J.R. Smith a good laugh.

As detailed by Nick Friar of Celtics Wire, SportsCenter shared the video of the action on its Instagram, to which Smith responded with a fair amount of LOL emojis followed by an untoward comment obviously aimed at Smart:

Marcus Smart, DeAndre' Bembry

Marcus Smart and J.R. Smith are not exactly the best of friends. These two almost came to blows when the Celtics and Cavs faced off a few months ago, and it does not appear that they have settled their differences since then.

Smart's intense and highly volatile style of play was on full display again on Saturday, and unfortunately for him, his inability to hold back his temper led to an early shower for him. On the other hand, though, it was a welcome sight for Smith, who could not help but take a shot at his nemesis.

Smart was only able to take the court for 17 minutes on Saturday prior to his ejection, with the 24-year-old scoring only four points on 1-of-4 shooting. Smart also contributed four assists and a steal in the Celtics' 113-105 win against the Hawks.

There is no word yet if Smart will get an additional suspension for his actions, but he should at least expect a hefty fine for his latest on-court outburst.
