Otto Wallin did little to underline his status as a heavyweight contender as he worked his way to a lackluster eight-round decision over Kamil Sokolowski on the Williams-Eubank undercard in Cardiff. 

For Wallin, this fight was just about being active, having been out of the ring for nearly a year and having had a fight with Dillian Whyte scrapped in October. 

But the 31-year-old Brooklyn-based Swede, whose only loss was to Tyson Fury, did not seem interested in making a big impression and appeared to use the fight as just a sparring session. 

He never really raised the pace above ‘plodding’ as he used his jab, took advantage of his height advantage and only rarely opened up. 

Sokolowski had done well in three recent fights in the UK, looking desperately unlucky to lose a decision against David Adeleye, going the distance with Solomon Dacres and then breaking the unbeaten record of George Fox. Wallin, though, was a different level altogether. 

The Polish boxer seemed a bit more intimidated by Wallin, although if he had been more active he might have created some problems, or at least woken Wallin up. 

Referee Reece Carter scored it 79-74 for Wallin. 

Samuel Antwi made a successful first defence of his English welterweight title after a gruelling ten-rounder against Conah Walker. 

The action was brutal from the opening bell, Walker walking forward and throwing hard punches non-stop and forcing Antwi to box with his back to the ropes throughout. 

But while Walker had the better of the first two rounds, Antwi landed the cleaner shots throughout the middle rounds and took advantage of any openings Walker left when he missed. 

Still, Walker never stopped trying, turning things back his way several times and doing well when he emptied the tank in the final rounds. 

Judges Victor Loughlin and Chris Jones scored it 96-95 and 96-94 respectively, while scoring referee Reece Carter had it 97-94 to give Antwi a unanimous decision. 

Harlem Eubank, the cousin of Chris, moved to 12-0 as a professional at the expense of 40-year-old Viroel Simion, who was pulled out by his corner after five rounds in the super-lightweight show-opener that was scheduled for eight.  

Eubank is trained by Adam Booth, who also trains Liam Williams, which has created some awkwardness ahead of this night, with Booth not in Harlem’s corner. 

Simion once went a tough 12 rounds with Scott Quigg on the undercard of Joshua-Klitschko in 2017, but has slipped into journeyman status since.  

He was negative early on against Eubank, who was able to dominate on workrate alone. Simion started the fourth round with more aggression and caught Eubank with a decent left hook on the counter, which gave Eubank something to think about. 

But Eubank stepped on the gas in the fifth as he landed to head and body. And while Simion did not go down, Eubank bashed the resistance out of him and Simion retired at the end of the round. The referee was Chris Jones.
