Tyson Fury will be looking to cause Deontay Wilder a world of pain on Saturday night. 

The pair collide in Las Vegas for their long-awaited rematch at the MGM Grand, in what's expected to be the biggest fight of the year. 

We've already seen bad blood at the pre-match news conference, while the two won't be allowed to face off at Friday's weigh-in as organisers move to prevent any possible on-stage clash. 

Don't get us wrong, these are two really dangerous men.

But ahead of Saturday's fight, Fury also showed off a different side to himself. 

In the second episode of his new ITV documentary 'Tyson Fury: The Gypsy King', he's filmed sitting at a restaurant in Marbella, being offered two live lobsters for dinner. 

The boxer purchases them for €200 (£158) - but not to eat. Instead, he takes them away from the restaurant and releases the crustaceans back into the sea. 

Check out the clip below: 

What a brilliant deed from the heavyweight. 

Justifying his actions walking back from the beach, Fury says: "It was alive and it was going to get burned alive and I didn't want to burn them.

"I don't like killing animals. It's not often you can do something good in life and today, that was a good deed and it only cost me €200." 

Ironically, the Gypsy King then says: "I'm going to have steak" as he sits back down at the restaurant. We'll let him off this time, though.

Strangely, the two lobsters he rescued were named Cristiano Ronaldo and Lionel Messi. Nope, we're not entirely sure why, either. 

While Fury showed off his soft side during that documentary, you can bet he'll be anything but nice when he finally steps into the ring with Wilder on Saturday night.
