The Logan Paul vs. KSI rematch is FINALLY SET -- it's going down at Staples Center on Nov. 9 ... and this time, it won't be counted as an amateur bout, this is a PRO fight!!!
Remember, the two social media superstars clashed in England back in August 2018 and fought to a draw in a pretty solid match on YouTube Pay-Per-View.
The fight did so well, even UFC honcho Dana White praised the guys for attracting a pretty big audience ... not an easy feat for people with no real fighting experience.
