The heavyweight champion was speaking at a press conference ahead of his fight next month against Dillian Whyte — who did not show up.
Asked about former opponent Wladimir and his brother Vitali taking up arms to defend Ukraine with fellow heavyweight Oleksandr Usyk, Fury said, “[It’s] fantastic. I’ll be the first to join if England gets involved, or America.
“I’ll be first in line for the job, my dad will be first in line for the job, and all the boys.
“We’ll all sign up to defend — that’s what I have to say.
“I think if you come from this country, live in this country, stand up for it. Love your wife and fight for your country.”
Wladimir — who had an undefeated 11-year run in the ring ended by Fury — recently called on the world to “act now” to help defend Ukraine against the Russian invasion.
In a video posted on Instagram on Saturday, the 45-year-old — whose brother Vitali is the mayor of Kiev — said, “I’m Wladimir Klitschko, and I’m addressing the world to stop this war that Russia has started.” .
“Just today, civilians were shot by rockets, with special operations, civilians were killed. And this is happening in the heart of Europe.
“There is no time to wait because this will lead to a humanitarian catastrophe.
“You must act now to stop Russian aggression with everything you can get now.
“In an hour, or tomorrow, it will be too late.
“Please take action now. Do not wait. Act now. Stop this war.”
IBF, WBO and WBA champion Oleksandr Usyk also suspended his career to defend his homeland and also pleaded for the war to end.
In a video posted on Instagram, the 35-year-old said, “Dear Ukraine and Ukrainians, some wrote about my escape. This is not true, I went on a work trip and now I am back. I am home.
“Friends, we must unite and overcome this, because we are facing exceptional difficulties.
“I am very overwhelmed with emotions and I am very worried for my country and for our people. Friends, we must stop this war and we must do it together.”
