'The Gypsy King' Tyson Fury (29-0) placed a video message online directed to WBC heavyweight champion Deontay Wilder (41-0-1).
The 31-year-old Brit told his American rival: "This a message to address Deontay Wilder's recent comments on how I don't want to fight him or how afraid of him I am. If I was afraid of ya I wouldn't have fought ya after having three-year out the ring and beat ya in your own country, but you had to rob me and give me a draw.
"So I don't know why on earth you would think I'd be bothered about you. Just get through your fight with Ortiz, do your own thing. Stop using my name for relevance. You should be on 20% but I'm not, I'm giving you a fair share because I'm a fair man.
"Crack on with your own business. And I'll see you February 22nd to finish what I started. This time you're gonna' get smashed, ya big bum dosser. End of."
Fury and Wilder both met in the ring in December 2018, with the WBC heavyweight championship contest ending in a draw. Fury dominated the contest, like he did the first time he challenged for world titles against Wladimir Klitschko in 2015, winning the WBA, IBF, WBO, IBO world titles, as well as The Ring Magazine belt. However, a last-round knockdown against 'The Bronze Bomber' ended up costing the outspoken Brit the decision on the judges' scorecards and the one world title that he hasn't held aloft before.
The pair are set to clash again on February 22 next year.
Since their encounter, Fury has gone on to blast unbeaten German Tom Schwarz (24-0) away in a one-sided second-round TKO victory in his Las Vegas debut, then he had a scrap of it with unbeaten Swede Otto Wallin (20-0), suffering from an horrendous cut early on in the fight and having to fight his way to a unanimous decision win in a bloodied, ugly fight.
Alabama's 34-year-old long-reigning WBC world champion Wilder destroyed Dominic Breazeale (20-1) in one-round, five months after his draw with Fury, and is all set to defend his green and gold belt to former victim Luis Ortiz (31-1) on November 23 at the MGM Grand in Vegas.
If the fearsome puncher, who has 40 KOs from 42 fights, can get past 'King Kong' again, then fight fans can expect to see Wilder-Fury 2 in February 2020.
