The two were scheduled for six rounds to help raise money for the Anthony Walker Foundation.
And it was purposely staged at the exact same time as Jake Paul’s fight with Andre August, which he won in the first round.
KSI has boxed eight times, most recently in October when he lost for the first time, against Tommy Fury.
Whereas Speed – a streamer known for his obsession with Cristiano Ronaldo – has hardly laced up a pair of gloves.
And it showed.
Speed ran around the ring for three rounds while falling to the floor whenever KSI landed a half meaningful body shot.
The social media star was utterly exhausted during the half way point when KSI decided to call it off.
He said: “It takes a big man to get in the ring with me. Many have tried, many have failed and according to judges, someone was victorious.”
But an emotional Speed said: “It’s not over yet. Get back in the ring.”

KSI responded: “I’m proud of you, you did a huge thing. We had over 100,000 watching our spar. I want you to take this and let it fuel you.
“You know what? With your tenacity I’m going to tap out. You win.”
Speed was not happy with the sympathy vote and demanded the full six rounds be completed.
He then burst into tears and stormed out of the gym to end the night on a sour note.
