Junior middleweight contender Carson Jones is backing his former rival, IBF welterweight champion Kell Brook (36-1, 25 KOs), to defeat mandatory challenger Errol Spence (21-0, 18 KOs).

Brook will have the home advantage, when he face Spence on May 27th in Sheffield.

Jones faced Brook on two occasions. They first fought in July of 2012. Brook barely escaped a knockout loss as he physically fell apart in the late rounds. He struggled to make the welterweight limit for that fight and walked away with a close twelve round majority decision.

They fought again a year later, this time at 151 pounds, and Brook redeemed himself with an eight round knockout.

In his last fight, Brook suffered his first career defeat when he was stopped in five rounds by middleweight king Gennady Golovkin. Brook moved up by two full weight divisions for that bout. He suffered a fractured orbital bone and his corner finally stopped the fight in the fifth.

Jones is picking experience and size to win, but he does admits that he's a little biased.

"Honestly, I think he beats Errol Spence. I'm always going to pull for Brook, considering our paths. I hope he wins. I fought Kell Brook twice. Aside from Golovkin, people can argue that I beat him the first fight. So every time he does great, I do great. He can be American, Chinese, whatever.. I don't care. If its going to benefit me and make me look better, and help put my name out there, I'm all for it," Jones told BaylorIC Worldwide Television.

"I don't think that it's going to be easy at all for either fighter, but I think Brook has more experience in those types of fights. Brook is a tough SOB. He didn't get dropped by me. And he may have broken his orbital bone, but he never went down against Gennady. He is one tough competitor. Unless he has an issue with his eye still, I don't think Spence has the power to put him on his ass."

"I think Spence is a smaller guy and I really think experience is what's going to help Brook win this fight. He knows how to dig deep and how to grind a fight out, and Spence doesn't know what that is yet. Spence is taller, but I disagree that he's bigger. Brook has had issues with making 147 and you've never heard that about Spence. I'm not saying Spence doesn't have any issues [making weight]. But for Brook it's a grind to get down from those last two pounds. As far as being the bigger man, I think Kell has the weight advantage."
