The 22 year-old brute kept Guinn off with his exceptional jab and had no trouble staying away from the veteran’s punching to breeze through each of the ten rounds and continue his steady progress.
Fury is lined up to fight again next month on the Billy Joe Saunders v Max Bursak undercard at Copper Box on April 30 in a deal that sees the cousin of top division king Tyson fight on subscription channel BoxNation.
The elder Fury stole the show during the fight by carrying the ring card girls board around at one point, even giving the crowd a shimmy as he did so, to the amusement of just a handful of fans.
Co-feature to the Nick Blackwell v Chris Eubank Jr British middleweight title clash, the Fury v Guinn fight was delayed by around half an hour and blacked out from TV coverage.
Blackwell was taken out on a stretcher and subsequently taken to hospital after a brutal beating.
