Hard-hitting Israel Duffus stopped Samuel Clarkson in round 2 Saturday night at the Toyota Music Factory in Irving, Texas.

With the victory, Duffus improves to 20-6, 17 knockouts.

The fight was a clash between fringe light heavyweights, who have accumulated a mix of impressive victories and disappointing losses. Duffus, who is originally from Panama and now resides in Los Angeles, had lost his previous two bouts to unbeaten fighters Charles Foster and Richard Rivera. He had won his previous eight bouts.

Clarkson, who resides in nearby Cedar Hill, entered the Duffus fight having won three of his previous four bouts. The only blemish was a knockout loss to cruiserweight contender Ryad Mehry in December 2018.

The 29-year-old did defeat former world title challenger Cedric Agnew by split-decision in February 2015, but suffered losses to Jesse Hart (2014) and to WBA light heavyweight titleholder Dmitry Bivol in April 2017.

Both fighters had their moments in the opening round, but Duffus, who is trained by Freddie Roach, was the aggressor, backing Clarkson up against the ropes and landing several right crosses to the head.

About midway through the second round, a sweeping overhand right to the head dropped Clarkson against the ropes. Clarkson beat the count and attempted to fight back, but the 26-year-old Duffus again pressed the action, landing thudding punches.

Moments later, a straight right hand split the guard and landed on the chin of Clarkson, dropping him again to the canvas. Clarkson stood up on wobbly legs, prompting referee Neal Young to wave the fight off at 2:07.

Clarkson drops to 22-6, 15 KOs.

In a clash of unbeaten middleweights, Evan Holyfield defeated Dylan Carlson by unanimous decision over four rounds.

Scores were 40-36, 40-36, and 39-37 for Holyfield (4-0, 3 KOs), who is the son of former undisputed heavyweight champion Evander Holyfield, who was sitting ringside for the fight.

Carlson (1-1-1, 1 KO), who grew up in Omaha, Nebraska, was game throughout most the fight, but Holyfield landed the more-effective punches and utilized better ring generalship.

In cruiserweight action, former amateur standout Tristan Kalkreuth of Duncanville, Texas stopped Chicago’s Johnny Jackson (1-1-1, 1 KO) in the opening round. Kalkreuth (5-0, 4 KOs), who signed a promotional deal with Golden Boy Promotions, dropped Jackson twice before the fight was stopped.

The ‘Night to Fight’ card was a co-promotion between Main Events and Bash Boxing. Proceeds from the event went to Ring of Hope, a non-profit organization that steers at-risk youth and teenagers to boxing programs in the Dallas-Fort Worth area. Clarkson is involved in these programs, visiting gyms and mentoring participants in the programs when he is not training.

Al Bernstein and Paulie Malignaggi of Showtime, along with BoxingScene’s Manouk Akopyan called the action from ringside for Integrated Sports Pay-Per-View.
