The first WBSS super middleweight match featured Callum Smith and Erik Skoglund, two young undefeated fighters, competing for a spot in the semifinals. At the official weigh-in, Smith hit the scales at 167 3⁄5 lbs, while Skoglund weighed-in around 167 3⁄5 lbs. The fight took place at Echo Arena in Liverpool and was announced by Jimmy Lennon Jr.[9]

Smith beat Skoglund by unanimous decision to win one of four quarter-finals in front of his home crowd in Liverpool. The officials scored the fight 116–112, 117–110 and 117–111 all in favor of Smith. Now unbeaten in 23 bouts, Smith also claimed the WBC Diamond belt and became the first semi-finalist in the super middleweight World Boxing Super Series. Early on, the fight appeared to be a mismatch with Smith outclassing his opponent. However, Skoglund got himself into the fight in the middle rounds behind his consistent jab and head movement, giving Smith a bloody nose. Smith would make his own surge late in the fight, scoring a knockdown in round 11 and earning a clear unanimous decision.[10][11]

In the lead-up to the fight, Ahmet Öner, Yıldırım's manager, got into a one-sided confrontation with Eubank's camp at a press conference. Öner called Eubank arrogant, threatened to knock someone out, and yelled "When you laugh, you son of a bitch, I fuck your wife in your bed!" at a man off-stage.[12] At the weigh-in, Eubank tipped the scales at 167 7⁄10 lbs, while Yıldırım weighed in at 168 lbs.[13]

On fight night, Eubank blasted Yıldırım, knocking him out in round 3. Eubank dropped his opponent with an uppercut in the first round, and finished him with a flurry of punches punctuated with a left hook in round 3.[14]

Upon being announced, the decision was booed by the audience at the Hanns-Martin-Schleyer-Halle. A brawl broke out in the stands moments before the main event.[15]

The win set up another domestic showdown for Groves, who is scheduled to face Eubank in the semifinals.[17][18]

The undercard features tournament alternate Patrick Nielsen taking on local fighter John Ryder. Ryder blasted Nielsen, dropping him after two rounds. Nielsen was then hurt in round five by a right hook, which also dislodged his gumshield. Ryder then pounced on Nielsen, who wasn't defending himself and went down and out.[19]

Brähmer defeats Brant via UD (119–109, 118–110, 116–112).

The final Super Series quarterfinal featured Jürgen Brähmer going against Robert Brant. Both competitors had recently fought at other weights, with Brähmer being a former light heavyweight world champion and Brant a fringe middleweight contender. Brähmer's last fight at super middleweight was a decision win over Mario Veit. At the weigh-in, Brähmer weighed 166 9⁄10 lb, while Brant tipped the scales at 166 lb even.[20]

Brähmer got a dominant decision win, outboxing and outworking Brant over twelve rounds.[21] Brant was unable to cope with Brähmer's refined technique, and he eventually seemed to tire out. Brant had only fought ten rounds once before and he had never fought twelve rounds.[22] Brähmer's promoter and tournament organizer, Kalle Sauerland, called it Brähmer's best performance of all time.[23]

Tournament reserve Vincent Feigenbutz picked up a win on the undercard, with a round 11 TKO over Gastón Vega.
