Tyson Fury admits he gets "turned on" by facing the unknown and that is why he will not underestimate Otto Wallin in their heavyweight fight in Las Vegas.

The Swede has a 20-bout unbeaten record, which includes 13 knockouts, but none have been anywhere near this level and Fury's trainer Ben Davis said even he struggled to find footage of the unheard of 28-year-old.

Fury has taken the fight as stop-gap before an expected rematch against Deontay Wilder in February and while he knows little about his opponent that merely adds to the excitement for the Mancunian.

It was nine pounds lighter than when he fought Tom Schwarz on his first appearance in Las Vegas in June, and just under the 256.5lbs he was against Deontay Wilder last December. Swede Wallin tipped the scales at 236 (16st 8oz).

Fury has embraced a Mexican theme since his arrival in the city as he fights on the country's Independence Day weekend and for the second time this week appeared in a lucha libre wrestling mask.

Having stepped off the scales Fury then grabbed the microphone to say, in an faux American accent: "In less than 24 hours from now Otto Wallin will feel the fury.

"Bob, get the steel cage out Bob (veteran American promoter Bob Arun) so this bum doesn't run away."
