UK light-heavyweight Joshua Buatsi earned a win yet unimpressive beginning to life under new promoters with a points victory over Zach Parker in Manchester.
The Olympic bronze medallist's work rate likely gained him a judges' verdict in a competitive 10-round bout at the boxing arena.
But Parker had his moments, landing some telling clean blows in a match where the techniques failed to mesh, with constant grabbing disrupting the contest.
The scoring judges judged it 96-94 in favor to Buatsi, with the third a 95-95 draw.
"It wasn't my finest performance but what do champions do? They win," the victor commented in the ringside as he was greeted with disapproval from the audience.
The Londoner bounced back after his maiden career setback - an thrilling contest with his previous opponent in last winter - to claim a 20th pro success.
Several boxing experts believed Parker, thirty-one, merited the decision but the contender experienced the second loss of his 28-match professional journey.
His career development has stalled in the past few years through contract problems and extended periods of inactivity.
Previously predicted as the rising talent of the British fight scene, he now stands trying to achieve expectations - possibly in what feels like a ultimate opportunity - under new promotional backing.
He opened tentatively, with both competitors willing to overcommit in a cagey opening few rounds.
Parker, whose single earlier setback came at super middleweight against his former opponent in 2022 after suffering a hand injury during the bout, was participating in his second fight at the higher weight class.
By the middle rounds, Parker had stayed in contention, creating difficulties for the favorite, who worked behind a protective stance to narrowly win the more effective rounds.
The crowd's patience diminished amid frequent holding, with the challenger slipping to the canvas several times during grappling.
Parker closed well, but several stanzas were difficult to score. Nevertheless, ex-champion Carl Frampton - providing analysis for Dazn - had it strongly leaning for Parker, scoring for Buatsi just one round.
Buatsi moves on, but with the caliber of heavy hitter David Benavidez, and Russian star Bivol ruling the division, the road to world glory - on this evidence - still seems difficult.
In the supporting bout, Arthur overcame Rea by split-decision in a outstanding all-Manchester battle to secure the European light-heavyweight belt.
The venue fell silent for a profoundly moving memorial before the fight as a bell ceremony sounded in honor of local hero Hatton, who passed away 46 years old in last month.
It was the premier televised boxing event in the urban center since Hatton's death. As the final chime disappeared, the quiet became a chant of "only one Hatton".
The competition during the bout equaled the emotion. The eventual winner was floored by a significant blow squarely on the chin in the initial stage, rising shakily to his position on the referee's count.
But the traditional red shorts of Arthur soon pressed ahead again. Across the ring, Rea - in competitive blue - was marked up quickly, heavy swelling appearing under his face as the pair exchanged powerful shots.
The challenger, 27, connected with strong blows but Arthur, 34, fought fire with fire with stinging uppercuts as the pace rarely dropped over twelve rounds.
Arthur barely secured the result with scoring tallies of draw, narrow lead and wider gap, but each competitor were relentless and brave, all the qualities their idol Hatton represented.
