KSI and Logan Paul battle it out in their highly-anticipated rematch in Los Angeles tonight.
The Youtube stars clashed in Manchester last year but their amateur bout ended in a draw.
KSI and Paul will now go head-to-head once again, this time in a professional fight at the iconic Staples Center.
The undercard features British boxing champion Billy Joe Saunders, who will defend his WBO super-middleweight title against Marcelo Esteban Coceres.
What time are the ring walks?
KSI and Logan Paul are expected to make their ring walks around 4am GMT (Sunday).
However, this time could change depending on how the undercard plays out.
What time will the fight start?
KSI vs Paul will get underway shortly after the ring walks are completed.
So, if the ring walks take place at 4am, expect the main event to start around 4.10am.
What have the fighters been saying?
KSI: “This is the hardest thing I’ve done in my life.
“This camp has pushed me to the edge. I’ve never worked so hard in my life.
“Mentally I’ve reached a new point, I’m not afraid to get hit. I’m not afraid to get punched in the face or take a big body shot. I’m ready to f*** you up.”
Logan Paul: “I wish I felt anxiety, it would make me feel human but unfortunately you’re not dealing with a human, you’re dealing with an animal.
“There are so many ways this fight can end. I can answer this question and say knockout, I can say TKO, I can answer the question and say this fight goes the distance, but to be honest we are prepared for anything.
“My condition is top-notch, if you want to go six rounds, I can go six rounds, but I promise it will not be good for your health.”
