CALLUM WALSH PASSED the trickiest test of his almost-five-year professional boxing career, earning a unanimous-decision victory over England’s former European champion Tyler Denny at Dublin’s 3Arena. Despite touching the canvas in unusual fashion in the first round, Walsh was well worth the wide gap on the judges’ scorecards. ‘King Callum’ began with typical, high-paced aggression and landed significant blows on Denny before he found himself on the canvas in the opening round. Denny, while conspicuously the larger man, has just one knockout victory to his name, giving Walsh little cause to respect his power. The elder McKenna brother subsequently called for a fight against Callum Walsh, who, at that point, was yet to perform.
