Tomorrow night's WBA light-middleweight fight between Anthony Mundine and American Shane Mosley is off with Mosley having left Sydney following a row over cash with promoters.
The 42-year-old Mosley is a three-time world champion and he and Mundine were due to appear for the official fight weigh in this afternoon.
One of the fight's backers former Australian boxer Jeff Fenech says he's now $500 thousand out of pocket.
Fenech says he put up the money in advance because promoter Vlad Warton couldn't afford it.
But Mosley has flown home today claiming he wasn't paid the balance of his $1 million purse before the fight.
Fenech, says he didn't know Mosley was due to be paid before the fight.
