Heavyweight contender Tyson Fury makes it clear that he's very serious about his recent talk of retiring from the sport in a few more fights.

Fury is back in the ring on Saturday night at the MGM Grand in Las Vegas, when he challenges WBC world champion Deontay Wilder in a rematch.

They fought to a controversial twelve round split draw in December of 2018.

According to Fury, there are three fights remaining on his co-promotional deal with Top Rank and ESPN. Frank Warren of the UK is Fury's lead promoter.

Back in 2018, Fury snapped a layoff of over two years. In his third fight of that year, he faced Wilder.

Fury does not see a reason to continue his career, after beating Wilder and doing a few more fights. Among those final few fights, he would like to unify with WBO, IBF, IBO, WBA champion Anthony Joshua.

"I've not got an age, but I've got three fights left on my contract with ESPN," Fury told ESPN's Ariel Helwani on Monday. "And after that, I will seriously think about walking away."

So why, on the brink of his biggest opportunity to date and a revitalized heavyweight division, would Fury consider walking away during the biggest money-making window of his career? I don't need to fight anymore. What is the point? What am I going to gain from it?

" When I beat Wilder on Saturday, I'll have completed the game. The game will be completed. I'll have won every single belt there is to win in the game, from minor to major, and I'll have won The Ring magazine belt twice -- becoming only the second man in history to do that, me and Muhammad Ali. Even after this win on Saturday, there's nothing more to do. Nothing more to be gained."
