Boston Celtics forward Jared Sullinger is on the cusp of being suspended after being whistled for a pair of flagrant-1 foul calls - an automatic ejection - in the third quarter of Boston's game at Denver on Tuesday.

It raises Sullinger's flagrant foul point total to five points. The next flagrant foul he is whistled for this season will result in him being suspended for at least one game.

If Sullinger is whistled for a flagrant-1 foul, he will be suspended for the next game following the one in which his point total exceeded five points.

He could potentially wind up being suspended for two games if the next flagrant foul he commits is considered a flagrant-2 which is an automatic ejection from the game.
