UK light-heavyweight Joshua Buatsi earned a win yet unimpressive start to life under recent management with a points victory over Zach Parker in Manchester.
The Olympic medal winner's work rate appeared to earn him a split decision in a tight 10-round bout at the Manchester venue.
But Parker landed significant shots, delivering effective individual punches in a match where the techniques didn't complement each other, with excessive holding spoiling the contest.
Two judges judged it 96-94 to the winner, with the remaining official a even score.
"It wasn't my finest display but what do champions do? They prevail," Buatsi commented in the ring as he was greeted with disapproval from the audience.
The Londoner bounced back after his initial pro loss - an memorable fight with his previous opponent in last winter - to earn a twentieth professional win.
Various analysts thought the challenger, thirty-one, should have been awarded the victory but the contender endured the second defeat of his 28-match professional journey.
The fighter's advancement has stalled in recent times through contract problems and long spells of inactivity.
Previously predicted as the next star of UK boxing, he now finds himself trying to achieve expectations - maybe in what appears to be a final roll of the dice - under recent support.
He began cautiously, with the two boxers prepared to overcommit in a cagey opening few rounds.
Parker, whose sole prior loss came at super middleweight against John Ryder in 2022 after suffering a hand injury mid-fight, was competing in only his second appearance at light-heavyweight.
By the halfway stage, the underdog had kept it close, creating difficulties for Buatsi, who utilized a protective stance to edge the better stanzas.
The audience's tolerance wore thin because of regular grabbing, with Parker slipping to the canvas multiple occasions during grappling.
The underdog finished the stronger, but several stanzas were difficult to score. Nevertheless, previous titleholder Carl Frampton - providing analysis for the broadcast network - had it particularly wide for Parker, awarding Buatsi just a single round.
The victor moves on, but with the presence of power puncher David Benavidez, and Russian champion Bivol ruling the division, the path to championship success - judging by this showing - still seems difficult.
In the supporting bout, Lyndon Arthur overcame Rea by split-decision in a outstanding local rivalry battle to win the continental championship.
The stadium became quiet for a deeply poignant homage before the fight as ten bells rang in memory of Manchester's own Hatton, who died at age 46 in recently.
It was the first major televised boxing event in the urban center since the passing of Hatton. As the last bell disappeared, the stillness became a chant of "there's only one Ricky Hatton".
The competition within the ring reflected the sentiment. The eventual winner was floored by a powerful punch directly to the face in the second round, getting up unsteadily to his feet on the eight count.
But the red-colored equipment of Arthur soon advanced again. Across the ring, the opponent - in opposing blue - was damaged soon, significant bruising appearing under his eye as the duo exchanged hard punches.
Rea, twenty-seven, delivered effective strikes but Arthur, 34, matched the intensity with effective uppercuts as the action seldom decreased over 12 rounds.
Arthur narrowly won the decision with scoring tallies of 114-114, narrow lead and wider gap, but each competitor were persistent and courageous, exactly what their idol Hatton embodied.
