Inspired by the success of the format, KSI publicly challenged the well-known American YouTuber Logan Paul to a fight. The fight took place with great public attention and ended in a tie. Then there was a rematch between the two in 2019, which this time was carried out as a professional boxing match and contained an undercard from various other professional boxing matches.
