Fulghum Stuns Unbeaten Pacheco in Carson to Crash the Super Middleweight Title Picture

Darius Fulghum walked into Diego Pacheco's backyard on Saturday night and walked out with his unbeaten record, his belts and his place in the super middleweight title picture. The Houston challenger outboxed the Los Angeles favourite over 12 rounds at Dignity Health Sports Park in Carson, California, winning a unanimous decision that nobody in the building had scripted for him.

Two judges scored the fight 115-112 for Fulghum and the third had it 114-113, all in his favour. The result improved Fulghum to 16-1-1 with 13 knockouts and handed Pacheco the first defeat of his professional career, dropping him to 26-1 with 19 knockouts. Fulghum also collected the WBC Silver and WBO International super middleweight titles Pacheco had carried into the fight, and the bout served as a WBA final eliminator at 168 pounds.

Pacheco had arrived in Carson as the house fighter in every sense. The card, promoted by Matchroom Boxing and shown on DAZN and TNT, was built around the 25-year-old from Los Angeles, a 6-foot-4 puncher with a six-inch reach advantage. Fulghum, by contrast, was cast as the credible but beatable opponent, the man brought in to give the hometown star rounds. From the opening bell, he refused the part.

The story of the fight was Fulghum's jab. Pacheco's jab had been the most talked-about weapon in the build-up, yet it was Fulghum who won that battle, out-landing Pacheco 82-63 with the jab over the 12 rounds, according to DAZN's punch statistics. He changed levels and used upper-body movement to slip inside Pacheco's reach, then worked at close quarters where the taller man's long arms gave him no leverage. Whenever Pacheco tried to reset at distance, Fulghum was already there with short, stinging shots.

Fulghum opened a cut under Pacheco's right eye with a sharp left hand in the third round, an early sign that the favourite was not going to have the comfortable evening his promoters had planned. Pacheco, trained by Hall of Fame fighter Buddy McGirt, answered with big right hands in the fourth and sixth rounds. Fulghum absorbed them, closed the distance again and kept working. A former wrestler, he used his strength on the inside to smother Pacheco and deny him the space to punch cleanly.

Pacheco's best spell came late in the eighth, when a pair of right hands probably won him the round and briefly suggested a momentum shift. Fulghum clinched, smothered the follow-up and kept moving, refusing to let the moment grow. In the ninth, he was deducted a point for punching behind the head as Pacheco dipped away, a decision that could have swung a close fight. On the two wider cards, Fulghum still had room to spare.

The championship rounds belonged to the challenger's composure. Fulghum got the better of a big exchange in the 10th, answering with a right hand and a jab before slipping Pacheco's return fire. In the 12th, Pacheco landed a few power right hands the judges could not ignore, but none of them hurt Fulghum or drove him back. Moments later, Fulghum landed his own right hand on Pacheco's cheek, a final statement of the control he had shown all night.

"I don't think you understand what I had to go through in this fight," Fulghum said afterwards. "I got this uniform on, King of Hearts. Man, I always say I got the most heart in boxing. I want to win so bad it's crazy. I'm just thankful they gave me the opportunity to come in and do my thing." On the jab battle that defined the night, he added: "That was the big talk of this fight, was about his jab, but I was like, 'I don't think he really knows, I got a great jab myself.'"

The result rearranges the super middleweight queue. The WBA sanctioned the Carson fight as a final eliminator, and Fulghum now stands behind current mandatory challenger Bektemir Melikuziev, who beat Fulghum in an eliminator in May 2025 and is still waiting for his shot at titleholder Jaime Munguia. Munguia is expected to meet Melikuziev early in 2027, so Fulghum's route to a world title is real but not immediate. Fulghum said afterwards he would welcome a shot at Munguia or WBC champion Canelo Alvarez, but the more immediate business may be a return with Pacheco: promoter Eddie Hearn said Matchroom will activate the rematch clause, with a second fight expected in 2027.

For Pacheco, the loss is a sharp check on a career that had been gathering speed. He had beaten Immanuwel Aleem in July in his first fight with McGirt in his corner, and he had twice turned down chances to fight for versions of world titles. None of that mattered once Fulghum took the fight to him from the first round. The favourite had no answer for the pressure, the jab or the inside strength, and by the final bell the upset was the product of 12 rounds of sustained control.

The co-feature delivered drama of its own. WBO flyweight champion Anthony Olascuaga retained his title with a unanimous decision over Yuberjen Martinez, scoring a knockdown in the final seconds of a fight the judges scored 115-112, 115-112 and 114-113, the same margins as the main event. Earlier, Charlie Sheehy shut out Jose Matias Romero over 10 rounds at lightweight, and heavyweight David Adeleye won widely over Alexander Flores in his Matchroom debut. But the night belonged to Fulghum, the underdog who came to Carson to spoil a showcase and left as a man the division must now take seriously.
