Fury is a massive betting favourite to extend his flawless professional record to 27-0 and if he does, Wilder be sat ringside to confront his fellow undefeated heavyweight.
The WBC champion is in Northern Ireland to watch Fury fight Francesco Pianeta on Saturday night and he made his presence felt at Friday's weigh-in.
Following an earlier clash between the unbeaten American boxer and Tyson Fury's father, both Deontay Wilder and Tyson himself had to be separated.
Wilder has targeted Fury since negotiations for a unification fight with IBF, WBA and WBO champion Anthony Joshua ended unsuccessfully.
He defeated Sefer Seferi on his return to the ring, and is now slated to fight Italian Francesco Pianeta on Saturday night.
Wilder shouted "Bomb Squad" as Fury took to the scales on Friday afternoon but Fury's father, John, took umbrage with the interruption and let "The Bronze Bomber" know all about it.
Following initial attempts to shout each other down, the 54-year-old Fury aggressively approached Wilder before he was restrained by a security guard and his son's trainer Ben Davison, and further shouting continued.
"Joshua's old news, the new kid in town is Fury".
The bookmakers see Wilder vs Fury as an nearly completely even contest with Betfair offering odds of 5/6 on the American and 10/11 on the Englishman.
Wilder will be ringside on Saturday, and is likely to be Fury's next opponent should he come out on top against Pianeta.
The second fight of Fury's comeback features prominently on the undercard of Carl Frampton's against Luke Jackson.
