Tommy Fury was less than impressed with KSI's return to the ring after the YouTuber stopped Swarmz in the second round.
KSI is fighting twice tonight, and will take on professional fighter Luis Pineda later, and had been expected to stop his first opponent in the first round. KSI did at least drop Swarmz in the opening three minutes but the former semi-professional footballer rose to beat the count and made it to the end of the session.
But when he was dumped on the canvas again in the second round, he gave no indication he wanted to continue, despite the pleas from his team. And Fury, who has been linked with a fight with KSI, took to social media to say simply: "What have I just seen?"
