He was scheduled to face long-time internet rival Alex Wassabi beforehand, but Wassabi was forced to pull out for an alleged concussion.The two fights were built as the first in a line of tune-ups before the endgame Jake Paul fight, with the former looking to outdo the latter who had his own fights with Tommy Fury and then Hasim Rahman Jr. canceled.The undercard also featured several other YouTubers battling one another, including 'Nightmare's' own brother Deji Olatunji against Fousey, and King Kenny against FaZe Sensei.Read on for the full card results. KSI Two Fights In One Night - Full card resultsKSI def. Luis Alcaraz Pineda via TKO in Round 3 DAZN Boxing@DAZNBoxing3-0. THE UNDEFEATED @KSI HE'S CALLED OUT EVERYBODY #KSI2Fights1Night39403383-0. THE UNDEFEATED @KSI 🎤HE'S CALLED OUT EVERYBODY 😱#KSI2Fights1Night https://t.co/XW7aDFBrD0In his second fight and the main event of the night, the 'Nightmare' completed a clean sweep of TKO victories in the third round against Luis Alcarez Pineda.His fight against Pineda witnessed even more knockouts than his first bout, after knocking Swarmz down just twice the undefeated fighter had his 'pro boxer' opponent on the floor an immense seven times before the final bell was rung.The knockdowns on paper reflect a different story to the actual fight, however, as Pineda farcically dropped to his knees three times in the opening round, claiming to be struck in the back of the head. It would appear the 'Nightmare' recognized the easy ride, performing push-ups as he waited for his opponent to find his feet in the third round.Slim Albaher def.

Swarmz refused to answer the count following the second knockdown, after struggling to find any form of rhythm from the opening bell.KSI also never appeared to find an opportunity to shine, with his opponent explicably turning his back for much of the fight and racking up warnings in doing so. Compared to his previous bouts against Logan Paul and Joe Weller, KSI appeared to take a more technical approach, leading with the jab before letting off stinging shots.The 'Nightmare' is now 3-0-1 in boxing.
