Any match could be cancelled even a day before the actual fight. But there will have to be very heavy reasons for it.
Gary Russell is a great fighter. Not only did he not succumb to Lomachenko's barrage of punches, he even managed to draw the fight at least to a single judge. The fight ended with a majority decision.
This is going to be Mark Magsayo's most challenging fight ever. He is undefeated but I also consider Russell undefeated. Loma is of different level so that's truly understandable to have lost to him. But Magsayo has a strong punch in him that could end the fight anytime.
I doubt if Magsayo can do a Lomachenko in this fight, Russell acknowledged Magsayo's power but he also said that it will not matter if he cannot land that punch, I don't think Russell will do a peek a boo he never did that on his past fights, he will take offense to neutralize and make Magsayo off-balance in his offense if Magsayo can take Russell punch as he did with Ceja he can go for a knockout.
Indeed, Magsayo is nowhere near the skills of Loma, so we don't have to compare. Magsayo has a lot to prove here, he was lucky in his last fight, now it's tougher and a bigger fight, let's see what he can do, can he still remain undefeated after this fight?
In order for us to have a good comparison of the 2, we need to see Magsayo becoming a champion first, and this is his chance to be a champion, that's therefore he has to work hard and strategies that Russell will not dominate him in this fight. I trust him to win because he is the hungry fighter and he will surely consider this fight as the most important fight to win.
