UK light-heavyweight Joshua Buatsi secured a victory yet disappointing start to life under new promoters with a unanimous decision over Zach Parker in the Manchester arena.
The Olympic medal winner's punch output appeared to earn him a judges' verdict in a tight 10-round bout at the Co-op Live Arena.
But the challenger had his moments, delivering effective individual punches in a fight where the styles didn't complement each other, with excessive holding marring the action.
Two judges had it 96-94 in favor to the winner, with the remaining official a 95-95 draw.
"It wasn't my best performance but how do champions respond? They succeed," the victor said in the ringside as he was greeted with boos from the audience.

Several boxing experts felt the challenger, thirty-one, deserved the decision but the British boxer endured the second setback of his 28-match professional journey.
The Champion Secures Triumph in Slow Match
The fighter's advancement has plateaued in recent years through management issues and extended periods of inactivity.

He began cautiously, with neither fighter ready to overcommit in a cagey early stages.
The challenger, whose sole prior loss came at the lower weight class against his former opponent in two years ago after damaging his hand in the contest, was competing in only his second appearance at light-heavyweight.
By the halfway stage, Parker had stayed in contention, making life awkward for Buatsi, who utilized a protective stance to narrowly win the cleaner periods.
The crowd's patience diminished amid constant clinching, with the challenger slipping to the canvas multiple occasions during close exchanges.
The underdog finished the stronger, but multiple periods were hard to judge. Although, previous titleholder the boxing analyst - commentating on Dazn - had it significantly in favor for the challenger, giving Buatsi just a single round.
The victor progresses, but with the presence of power puncher Benavidez, and Eastern European fighter Dmitry Bivol leading the category, the road to world glory - based on this performance - still seems difficult.
