The NBA has made multiple amendments to its so-called 'Hack-a-Shaq' policy over the past few years. Its latest will reduce 45 per cent of away-from-play fouls, according to commissioner Adam Silver. 

The current rule for away-from-the-play fouls applicable to the last two minutes of the fourth quarter (and last two minutes of any overtime) will be extended to the last two minutes of each period, the league announced on Tuesday. 

"In looking at the data and numerous potential solutions to combat the large increase in deliberate away-from-the-play foul situations, we believe these steps offer the most measured approach," NBA executive vice president Kiki VanDeWeghe said in a statement.

"The introduction of these new rules is designed to curb the increase in such fouls without eliminating the strategy entirely."

Additionally, for inbounds situations, a defensive foul at any point during the game that occurs before the ball is released by the inbounder will be administered in the same fashion as an away-from-the-play foul committed during the last two minutes of any period.

The flagrant foul rules will be used to protect against any dangerous or excessively hard deliberate fouls. It will presumptively be considered a flagrant foul if a player jumps on an opponent's back to commit a deliberate foul.
