New York City based Swedish heavyweight Otto Wallin (22-1) is going to stay busy, when he returns to action on February 5 in Cardiff, Wales, on the undercard to the middleweight grudge match between Chris Eubank and Liam Williams, which is being carried by Sky Sports.

Wallin's stablemate, unified middleweight champion Claressa Shields, appears in the co-feature. Both are promoted by Salita Promotions.

"The deal was finalized [on January 28]," reports Wallin. "I've known for some time now that I probably would fight on his date so I've trained well, As for Sokolowski, he's a tough guy who shouldn't be underestimated.

Wallin last fought about a year ago and outscored two-time world title challenger Dominic Breazeale. He was then very close to a fight against WBC Interim-champion Dillian Whyte last October.

But, the fight fell apart at the late hour when Whyte withdrew with a shoulder injury.

Their fight never got rescheduled, as Whyte had recently been confirmed as the mandatory challenger to WBC world champion Tyson Fury - which the British boxer saw the far more lucrative opportunity. The two Brits went to a record-breaking purse bid this past Friday.

In Sokolowski, Wallin faces a tough journeyman who while he loses more fights than he wins, always makes his opponents work hard to get a victory.
