The NBA is looking into how often players simulate fouls and whether or not officials can tell the difference.

``They're really difficult to determine in real time. They're meant to fool an official,'' Stu Jackson told reporters on Thursday. ``Are we going to be wrong more times than not? It's tough, but we're looking at it.''

FIBA already permits referees to issue a technical foul for flopping, a penalty that Jackson said the NBA is considering. Other sports, including soccer and hockey, also allow officials to penalize players who embellish fouls.

``We have so many more plays than you do in a football or soccer game and in a more intimate environment,'' said Jackson,
