Liam Wilson has accused rival Emanuel Navarrete of tampering with the scales to make weight for their world title fight in Phoenix.
The Australian caused a stir at Thursday's weigh-in when he tipped the scales at 126.3 pounds (57.29kg), almost three pounds lighter than the Mexican favourite and four pounds (almost 2kg) under the super featherweight limit.
A bemused Wilson said he had weighed in almost four pounds heavier on the same set of scales just 20 minutes before the official weigh-in for the WBO strap at Desert Diamond Arena.
