The sportsman had hired bosses at his usual transportation firm, Fusion Luxury Motors, to move his pricey car collection from Las Vegas to Miami, Florida, on Wednesday (07Oct15) when the truck's two trailers became engulfed in flames just outside Phoenix.

Photos obtained by editors at TMZ.com show all of the vehicles being transported, including Mayweather's Bentley, a custom Jeep and two Rolls Royce cars, completely burnt out.

Arizona State Troopers have revealed no one was injured in the fire, which is currently under investigation.

Representatives for Mayweather, Jr., who was recently spotted on vacation in Bora Bora with Justin Bieber, and Fusion Luxury Motors have yet to comment on the incident.
