Adonis Stevenson avenged his lone loss, knocking out Darnell Boone — the man who had shockingly stopped him nearly three years ago — and setting himself up for a shot at the light heavyweight championship. The rematch headlined a WealthTV televised card at the Bell Centre in Montreal, Canada.

The knockout came in the sixth round. Stevenson landed a left uppercut that left Boone stunned, his hands down at his sides, nothing standing in the way of the hard southpaw left cross that followed and finished him.

Stevenson, a 35-year-old originally from Haiti but now fighting out of Longueuil, Quebec, improves to 20-1 with 17 knockouts. He moves on toward a presumed shot at 175-pound champion Chad Dawson. Boone, 33, falls to 19-21-3 (8 KOs).

Eleider Alvarez fights out of Montreal, but he is originally from Colombia — and like many other boxers from that country, he carries devastating power.

This became quite evident as he scored a crushing stoppage of light heavyweight Nicholson Poulard with a single combination in the third-round.

The time of the stoppage was 2:08. Poulard had his back against the ropes, standing still long enough for Alvarez to lead with a jab and follow with a big right hand. Poulard rose at eight, but his legs clearly weren’t beneath him, leading the referee to wave the bout off.

Alvarez, 28, is now 12-0 with 8 knockouts. Poulard, 35, of Laval, Quebec, is now 19-4 (9 KOs).

Quebec heavyweight Didier Bence took an eight-round unanimous decision over Jonte Willis, who made Bence once again go the distance, as has been the norm so far in his pro career.

The scores were 78-73 (twice) and 76-75.

Bence was able to knock Willis down in the third, taking a slight step back and landing a good right hand as Willis was coming forward. Bence also had Willis wobbled badly in the final seconds of the fifth. Though Willis’ legs had him dancing around the ring, he remained on his feet. Willis survived, though, gave Bence difficult moments and won rounds on the cards.

Bence, 25, of Laval, Quebec, improves to 8-0 (2 KOs). Willis, 29, of Tacoma, Wash., falls to 9-5-1 (3 KOs).

Hughie Fury needed one and a half rounds — and one punch — to score his first pro victory.

The 6-foot-8 heavyweight, who is one inch shorter than his older cousin, heavyweight prospect Tyson Fury, scored a second-round stoppage over David Whittom.

About halfway into that round, Fury threw a pair of jabs that caused Whittom to duck down. It was unfortunate timing and placement for Whittom, allowing the lengthy Fury to leverage downward with a right hand to the side of Whittom’s head.

Whittom rose on unsteady legs, holding the ropes as he got off the canvas. But before the action could resume, his corner apparently stopped the bout.

Fury, 18, of Stockport, United Kingdom, is now 1-0 (1 KO). Whittom, 34, of Quebec City, is now 11-20-1 (7 KOs).

Sébastien Bouchard scored a four-round unanimous decision over Adam Grabiec in a bout that at times was more competitive than the scorecards might indicate.

The scores were 40-36 (twice) and 39-37.

Despite a record in which he has lost more than he’s won, Grabiec showed some initial resistance in the opening round, only to have that sucked out of him by uppercuts, body shots and a continued onslaught.

Yet Bouchard couldn’t put his junior-middleweight foe away, and Grabiec, emboldened, began to land some more right hands in the third and continued to battle through to the final bell. It wouldn’t be anywhere near enough to win, however.

Bouchard, 25, of Quebec, is now 5-0 (2 KOs). Grabiec, 29, of Poland, is now 3-7 (0 KOs).

It didn’t matter that Basilio Silva had been in more fights in 2013 than Mian Hussein had in his entire pro career — Hussein quickly proved he was better, scoring two knockdowns in the second round for an emphatic stoppage victory.

The time of the stoppage in this bout between 149-pounders was 1 minute and 24 seconds.

The southpaw Hussein was able to land both left hands and right hooks in the first round, and this would foreshadow the end for Silva in the second. Hussein scored an early knockdown in that round with a right hook followed by a left cross. Silva rose at five, but ultimately found himself tagged again with a right hook to the face and then a left that landed higher up on his face. Silva moved backward and then crashed to the canvas, his head recoiling after hitting the mat. That led the referee to stop the bout.

Hussain, 22, of Montreal, improves to 5-0 (4 KOs). Silva, 31, of the Dominican Republic, fell both figuratively and literally to 11-7 (9 KOs), with every sincle one of those bouts coming within the past 22 month

In the broadcast opener on WealthTV, bantamweight prospect Marc Pagcaliwangan defeated Jose Adan Fernandez when Fernandez quit after the first round due to what looked to be a hurt right hand.

Fernandez appeared to suffer the injury after landing a right hook on Pagcaliwangan, wincing on more than one occasion throughout the remainder of the stanza. Sure enough, Fernandez opted to call it a night once he made it back to his corner.

Pagcaliwangan, 22, of London, Ontario, is now 4-0 (4 KOs). Fernandez, 21, of the Dominican Republic, suffered his first pro defeat and is now 2-1 (zero KOs).
