The National Basketball League has stood down two referees and made an immediate rule change in the aftermath of Melbourne United's controversial last-second win over New Zealand Breakers on Sunday.

The Breakers led Melbourne until the final seconds when the game referees mistakenly assessed Breakers guard Corey Webster with a "dead ball foul" which gave Melbourne two shots and possession - a decision which allowed them to tie the game with Chris Goulding's free throws then make the winning play with the last possession from guard Stephen Holt.

A league review on Monday found Webster's foul happened at the same time as Melbourne's Majok Majok fouled Breakers' centre Alex Pledger to stop the clock - this means the two fouls should have cancelled each other out leaving the Breakers with the ball and still in the lead.
