Otto Wallin wasn’t an undefeated fighter, but he knew a win over Derek Chisora would push him back into the world title mix. Ultimately, he could have been right, but the long-faded contender had other ideas.

This past Saturday night, at the Co-op Live Arena in Manchester, Chisora (36-13, 23 KOs) and Wallin attempted to take each other's heads off in the main event.

Wallin, who walked into their showdown as a sizable favorite, believed he could box and move his way to a decision. Chisora though, forced him to get his hands dirty and fight on the inside, resulting in a wide points win on the night.

If you knew Wallin personally, you'd know that he’s usually wearing a gigantic smile. The humble and normally buoyant giant, however, was despondent. As he slinked onto the sofa in the backroom, Wallin (27-3, 15 KOs) was met with several cameras and microphones. The 34-year-old wouldn’t offer up any excuses. He simply tipped his cap in the direction of Chisora and gave him all of the credit in the world.

“I’m disappointed, I tried,” said Wallin during a post-fight interview with iFL TV. “It wasn't my night. Derek fought a great fight.”

Nothing was clicking for Wallin as his head bounced back repeatedly throughout those 12 rounds. Although he did kiss the canvas on two separate occasions, he peeled himself up and continued to fight. Showing resilience isn’t surprising coming from Wallin. The former heavyweight title challenger has shared the ring with some of the division’s biggest punchers, including Anthony Joshua, Tyson Fury, and Murat Gassiev.

The question now becomes, who hits the hardest? While not giving a concrete answer, he did admit when it comes to pure power, Chisora can bang with the best of them.

“He has good power. He’s definitely one of the biggest punchers that I’ve been in with.”
