In the 2nd quarter of Friday night's matchup with the Toronto Raptors Isaiah Thomas responded to a Demarre Carroll flagrant foul with fiery emotion and looked to make a "gun gesture" in the face of the Raptors forward. The NBA is reportedly looking into the situation:
NBA is gathering info on Boston's Isaiah Thomas apparently making gun gesture and pointing at Raptors DeMarre Carroll in 2Q last night.
Obviously gun violence in not a joke and simulating that shouldn't be taken lightly, but in the heat of the moment after an awful flagrant foul that sent Thomas sliding headfirst into the baseline I wouldn't read too much into it.
