Just like with technicals the league tracks a players flagrants. After 5 flagrant "points" the player is suspended for 1 game. The article didn't say and I don't know what is the limit in the playoffs.
NEW YORK -- Denver Nuggets forward Kenyon Martin was suspended for one game without pay Thursday for exceeding the flagrant foul points total with five.
Martin was assessed a flagrant foul/penalty one for striking Phoenix's Boris Diaw in the face Tuesday night in Denver's win over the Suns.
Martin now faces one-game suspensions for each additional flagrant foul.
