Deji lost his third fight in succession as he was beaten by debutant Alex Wassabi.
The brother of KSI had vowed to retire if he completed an unwanted hat-trick.
And it looked as if he might be controversially saved by the judges - but Wassabi was given the nod by split-decision.
Deji, in the southpaw stance, was the first to launch forward after a slow start.
But Wassabi replied well, forcing his more experienced opponent to clinch and he made the Londoner miss at the end of the round.
The fight descended into farce in the second round when a fan climbed into the ring, forcing the bout to be stopped.
Security dealt with the intruder and the bout was able to resume and it ultimately went the five-round distance.
One judge controversially scored the fight for Deji but the other two, rightly, awarded it to Wassabi.
Here are the rest of the results from a crazy card...
King Kenny vs Faze Temperrr
King Kenny received a huge welcome from his home crowd as he took to the ring against rival Faze Temperrr.
These two clashed over five rounds and arguably produced the best action of the night.
Faze Temperrr would argue he shaded the early stages before the bout burst into life in the fourth round as King Kenny began to find his rhythm and land the better shots.
Faze Temperrr finished with a flourish but once again the fight went the distance.
The judges were split with the third proving crucial as he gave King Kenny the nod.
RESULT: King Kenny beat Faze Temperrr by split decision
Vitaly vs Kristen Hanby
Vitaly had promised to end this one in the first 60 seconds but he soon realised that was going to be easier said than done.
He found himself two rounds down as Hanby 'danced around' and kept out of distance while managing to land slightly better shots.
But bizarrely Hanby then opted to start headbutting his opponent and was fortune not to be disqualified.
The fight ultimately went the four-round distance but the judges could not be split.
RESULT: Vitaly DREW with Kristen Hanby
Armz Korleone vs Minikon
The super-heavyweights served up a decent contest with Minikon starting the better.
This was just the tonic after the drama of the fight before (see below) and Armz Korleone gave the home crowd something to cheer about as he worked his way into the bout and began to take over.
He tired in the final round as Minikon came on strong at the bell - but it wasn't enough for the judges.
Armz Korleone took the win on the scorecards but was so exhausted he needed to be given oxygen at ringside.
RESULT: Armz Korleone beat Minikon by majority decision
Ryan Taylor vs DK Money
This was the first stoppage of the night - but not for the right reasons.
Taylor felt he had been hit low (he hadn't) and took matters into his own hands, headbutting DK Money in shocking scenes.
The fight was immediately called off and Taylor was disqualified.
The crowd reacted by going berserk as the event was plunged into chaos while the fighters left the ring and the announcer pleaded for calm.
RESULT: DK Money beat Ryan Taylor by disqualification
Anthony Taylor vs Jay Cucciniello
The less said about this one the better.
To be fair, the fight was organised at the last minute and the fighters were clearly in no shape or mood to take it too seriously.
After four rounds which amounted to little more than an exhibition, Cucciniello was given the nod by each of the judges.
RESULT: Cucciniello beat Taylor by unanimous decision
Stromedy vs Austin Sprinz
The second fight of the night proved a laborious affair as neither man was able to stamp their authority on the bout.
But it was Stromedy who began to find his rhythm in the second session as he landed a right hand.
Canadian Stromedy landed a left in the third round as he continued to edge a tight contest.
And instead of tiring in the fourth and final session, Stromedy found a second wind to make sure of the victory.
One judge scored the fight a draw but the other two gave the visitor the nod.
RESULT: Stromedy beat Austin Sprinz by majority decision
Halal Ham vs Salt Papi
Both men flew out of the traps and attempted to land big shots but there were instantly questions over their physical condition.
And it didn't take long for the pace to slow but it became evident that Papi had the upper hand as he sent the Brit stumbling with a left hand.
Salt Papi continued to control the second round, showing off his deceptively quick feet and hands as Halal Ham struggled to make an impact.
Halal Ham realised he was behind as the fight entered the third and final round but his urgency wasn't enough and Salt Papi took the win 30-27 on each of the three judges scorecards.
RESULT: Salt Papi beat Halal Ham by unanimous decision
