QUEBEC CITY, Canada —One and Done.

In a heavyweight grudge match Arslanbek Makhmudov knocked out Ricardo Brown in the first round at the Videotron Centre, Quebec City, on ESPN+.

From the opening bell, Makhmudov (20-2, 19 KOs), who had gone head-to-head in the press conference with Brown (12-1, 11 KOs), went after the Toronto-based Jamaican.

It wasn't pretty, in fact it was very crude. Brown didn't go far from his corner as both threw bombs. The more aggressive Makhmudov landed and hurt brown, ultimately dropping him heavily with a looping right hand onto the ropes. Despite making it to his feet, his legs weren't under him and referee Junior Padulo wisely curtailed the action at 1:57.

"I needed this, the last couple of loses, injuries, I don't lose confidence, when I lose in the amateurs, I come back stronger," Makhmudov said. "I need to go to the top again...anyone."

That furious finish ended the evening's undercard action, before Christian Mbilli clinched the WBC interim super middleweight world title with a one-round statement stoppage victory over Maciej Sulecki topping a busy bill of fights at the Videotron Centre on ESPN+.

Speaking of super middleweights, Steven Butler breathed new life into his career with a fourth-round knockout victory over Jose de Jesus Macias to exact sweet revenge.

The former two-time middleweight challenger had been tabbed to face promotional stablemate Erik Bazinyan but for the second time the fight fell through. Instead Butler met Macias, who knocked him out a round later on Mexican soil in January 2021.

This time, Butler (36-5-1, 30 KOs) started fast boxing behind his jab, mixing in several sharp right hands that got Macias (29-14-4, 15 KOs) attention.

Macias felt the need to try to put a dent in Butler and enjoyed a better second round notably landing a left hand that had Butler moved away and reset. The round drew to a close with both men trading punches, much to the joy of fans in attendance.

The third saw both stand center ring and look to land their best shots. It was Butler's greater activity but Macias looked dangerous.

Things turned irrevocably in Round 4 when Butler uncorked a huge overhand right that landed flush depositing the visitor onto the canvas in his corner. He was able to scramble to his feet but clearly worse for wear.

That proved a dangerous place to be against the power-punching Butler, who lived up to his "Bang Bang" moniker. He landed a quick fire combination as Macias pitched forward and the referee had seen enough, ending the fight at 1:33 of the same round.

Touted light heavyweight Wilkens Mathieu scored an impressive third round stoppage over Adagio McDonald.

Mathieu (14-0, 10 KOs) boxed well countering his French opponent with several clean shots in the opening round. McDonald ate every one of them and was unfazed. The pattern remained in the second with Mathieu, who is a Ring ambassador, using movement and picking his shots well.

Just as it looked like McDonald (8-2, 6 KOs) could take what was coming at him Mathieu broke through with a volley of punches dropping McDonald to the seat of his pants, prompting the referee to wave off the fight at 0:44 of Round 3.

You don't get paid overtime in this game...

Hot prospect Jhon Orobio showed why he's a Ring ambassador, stopping Zsolt Osadan in the opening round.

Orobio (14-0, 12 KOs), who is a Colombian-born junior welterweight, put an early dent in Osadan (27-4-1, 17), dropping him midway through the first round with a sharp counter right hand and then hurt him to the body, forcing the Slovakian import to bend over, when he stood up, he left himself open to a left hook that dropped him heavily.

Although he made it to his feet, he was in no position to continue and the fight was wisely called off at 2:57 of the first-round.

On a previously visit to Canada, Osadan had taken Mathieu St. Germain the 10-round distance but he was no match for Orobio, who is a blue chip prospect.

Christopher Guerrero left it late but overwhelmed tough Sandy Messaoud for a 10th-round stoppage.

Guerrero (15-0, 9 KOs), making his third appearance of the year, had to deal with the awkward and unorthodox French opponent.

Guerrero grew into the fight and came on strong in Round 3, when pressed the action notably landing a solid right hand snapped Messaoud's head back.

In the fourth round, Guerrero gained Messaoud's (20-9, 1 KO) attention with another big right hand. However, while he appeared to have the better of things, Messaoud made things difficult and ugly whenever he could.

Entering the final round Punchinggrace had Messaoud up by one point. Ultimately it proved a moot point when Guerrero poured on the pressure and hurt Messaoud with a pair of right hands, which saw him give way and reel into his corner where referee Alain Villeneuve listened to Messaaoud's corner and called a halt at 2:28 of the final round. It wasn't pretty but should serve as a good learning curve for the 24-year-old welterweight.

Leila Beaudoin scored a career-best win over seasoned veteran Elhem Mekhaled dropping the French lady three times en route to scoring a sixth-round stoppage.

The Canadian boxed well against Mekhaled, whose only losses came against Delfine Persoon (UD 10), Ring undisputed 130-pound titlist Alycia Baumgardner (UD 10) and, most recently, Chantelle Cameron (MD 10).

Beaudoin struck early in Round six and wouldn't let Mekhaled off the hook scoring two more knockdowns before referee Martin Forest intervened ending the fight at 1:07.

Afterwards, Beaudoin called out Baumgardner, who will defend her cadre of titles against Jennifer Miranda on July 11.

Rising lightweight Luis Santana was taking part in his first 10-round contest but need five to dismiss Eduardo Estrela.

Santana (14-0, 7 KOs) dropped Estrela (17-5, 1 KO) with a minute left in the first round with a looping right hand that sent his opponent sprawling backwards unable to stay on his feet.

Things didn't improve much in the second round for the Uruguayan, who touched down twice. Initially from a left hook and then again at the end of the round with a combination.

The end looked close but Estrela hung tough until Santana stepped on the action and bludgeoned him to the canvas. He made his way to his feet but referee Mike Griffin had seen enough, waving off the action at 2:03 of Round 5.

2024 Canadian Olympian Wyatt Sanford opened up the show with a dominant six-round unanimous decision over Andrejev.

Sanford (3-0, 2 KOs) used his jab to good effect early and then as the fight progressed put hurt Andrejev (4-2) with body and headshots. He was unable to drop or score the stoppage against the game visitor but walked away with a shutout decision 60-54 twice and 60-53.
