KSI was attacked while waiting to buy lunch during his recent trip to the US.

The YouTuber, who flew to the states to train with boxing legend Floyd Mayweather and meet with rival Logan Paul, was waiting for food at a branch of In’n’Out when an apparent fan ran up and sucker punched him – and it was all captured on film. However, the assailant was no match for KSI, who was able to fend off the worst of the attack.
