YouTube is unlikely to remove it as it is part of history that the fight happens regardless of what happened after the fight.
Haney is so devastated that he wants people to forget the fight happen but I doubt people will forget it, the fight will hound him for the rest of his boxing career.
Devin Haney is certainly more than devastated. His mind and heart has been very much destroyed! He has requested a champion on recess and cancelled the fight against Sandor Martin. Devin Haney will need more than 1 year vacation and an immediate rematch vs. King Ry if he wants his mind to return to normal. However, after the suspension and similar to what I have predicted before, there will be a rematch. There will be another knockout of Devin Haney by King Ry and there will be another dirty sample of urine from King Ry hehehehehehehe.
