Robert Helenius to fight Dereck Chisora on May 27

In 2011, Robert Helenius, then a fast-rising heavyweight contender, saw his momentum come to a grinding halt against Dereck Chisora.

Although Helenius won a split decision to claim the vacant European title in front of his fans in Helsinki, Finland, it was viewed by most as a blatant robbery, with Helenius being the beneficiary of a hometown decision.

Now, six years later, Chisora will have a chance to set the record straight when they meet in a scheduled 12-round rematch on May 27 at Hartwall Arena in Helsinki, site of their first fight, Team Sauerland announced on Friday.

"The first fight between Robert and Dereck was something special, and this promises to be even better," promoter Nisse Sauerland said. "They've got unfinished business, and on May 27, they've finally got the chance to settle the score."

Helenius (24-1, 15 KOs), 33, who was born in Sweden but fights out of Finland, went through long stretches of inactivity after the fight with Chisora, partly because of a shoulder injury. He also suffered his first defeat, a sixth-round knockout loss to former world title challenger Johann Duhaupas, last April. Helenius has won both of his fights since and aims to make it three in a row against his old rival.

"Chisora is a good fighter, and I'm expecting a tough fight, but I'm very confident I will win," Helenius said. "Before our first match, I injured my right shoulder and had to fight for 12 rounds with just one arm. If I was able to beat him with one arm, I don't see any problems beating him when I have two.

"I am in great shape now, and I feel stronger than ever. It's been a long road back since my shoulder operation, and I've been waiting a long time for an opportunity like this. I believe I am ready, and after I beat Chisora, I will be in a good position to challenge for the world title.''

Chisora (26-7, 18 KOs), 33, of England was impressive enough in the disputed loss to Helenius that he got a world title shot against then-titleholder Vitali Klitschko in his next fight but lost a lopsided unanimous decision in 2012.

Chisora has had his ups and downs since, and he has lost two of his last three bouts, both split decisions -- one to former title world challenger Kubrat Pulev, in May 2016, and the other to Dillian Whyte in December, in a brutal slugfest that challenged for fight of the year honors.

Chisora said he is ready to go back to Helsinki and earn the victory that eluded him last time.

"I'm looking forward to going back to Helsinki and putting on another great show for the fans," he said. "It's a beautiful city with a lot of beautiful people. We had a lot of fun last time, and everyone knows who really won that fight. He can make all the excuses he wants, but that won't help him on May 27.

"I feel like this is my time. I'm in my prime, and I can't wait. I might be relaxed now, but when I leave London, I'm going to war. When I get on that flight, I become a different person. Mr. Nice Guy is gone. It brings the vicious side out in me, and he'd better be ready."
