UK light heavyweight Joshua Buatsi secured a victory yet disappointing debut to his career under fresh promotional backing with a decision win over Zach Parker in Manchester.
The Olympic medal winner's activity level seemingly secured him a split decision in a competitive ten-round bout at the boxing arena.
But the challenger had his moments, connecting with powerful single shots in a fight where the techniques failed to mesh, with constant grabbing disrupting the fight.
The officials judged it 96-94 to the winner, with the final judge a 95-95.
"It wasn't my best display but what defines champions? They succeed," the victor said in the ring as he was faced disapproval from the crowd.
The Londoner got back to winning after his maiden career setback - an memorable fight with Callum Smith in last winter - to claim a 20th pro success.
Several boxing experts believed the challenger, 31, should have been awarded the win but the contender suffered the second loss of his 28-fight career.
The fighter's advancement has stalled in recent years through management issues and extended periods of lack of fights.
Previously predicted as the next star of the British fight scene, he now stands trying to fulfil that early promise - possibly in what feels like a last chance - under recent support.
He started carefully, with both competitors ready to be aggressive in a cagey early stages.
Parker, whose only previous defeat came at super-middleweight against his former opponent in 2022 after damaging his hand in the contest, was participating in his second fight at light-heavyweight.
By the fight's midpoint, the underdog had made it competitive, causing problems for the favorite, who utilized a solid defense to narrowly win the more effective periods.
The audience's tolerance decreased during frequent holding, with Parker going down multiple occasions during clinches.
The underdog ended stronger, but multiple periods were challenging to assess. However, previous titleholder the boxing analyst - commentating on the broadcast network - had it strongly leaning for Parker, giving Buatsi just only one stanza.
Buatsi moves on, but with the likes of power puncher Benavidez, and Eastern European fighter Dmitry Bivol dominating the weight class, the journey to titles - based on this performance - still appears challenging.
In the co-main event, Arthur overcame Bradley Rea by divided decision in a outstanding all-Manchester contest to secure the European light-heavyweight title.
The stadium fell silent for a profoundly moving homage ahead of the contest as a bell ceremony rang in remembrance of the city's native Hatton, who died 46 years old in last month.
It was the initial significant broadcast boxing event in the city since the passing of Hatton. As the last bell faded, the stillness transitioned to a roar of "there's only one Hatton".
The action within the ring matched the sentiment. The eventual winner was knocked down by a significant blow flush on the chin in the initial stage, standing uncertainly to his feet on the count of eight.
But the traditional red equipment of the fighter soon came forward again. On the opposite side, Rea - in opposing blue - was injured early, significant bruising developing under his orbital area as the duo traded punishing blows.
The challenger, twenty-seven, connected with strong blows but Arthur, thirty-four, responded in kind with effective uppercuts as the intensity hardly diminished over the full distance.
Arthur barely secured the verdict with official scores of draw, narrow lead and wider gap, but the two athletes were determined and courageous, exactly what their hero Hatton stood for.
