Folayang's original opponent, Ole Laursen, had to pull out due to a knee injury sustained in training, and his replacement is a completely different type of fighter.
Kwon is far more experienced than Laursen and is on a six fight win streak meaning that, on paper at least, he looks a more dangerous fighter. However despite the fact that Kwon has had over twice as many fights as Folayang, and has fought against much higher ranked opponents, I think that he is actually a better fight for the Filipino than Laursen would have been.
Why? Because Laursen is a very technical fighter who has won world titles at Muay Thai in kickboxing and had been in there with the best K-1 fighters in the world. His boxing is so good he was even invited to join the Philippines national team.
Kwon, by contrast, is much more wild, and I think that could play right into Folayang's hands. The Filipino likes a slug fest, and will probably look to stand and exchange briefly before shooting in and taking Kwon down.
I would make Kwon the favourite for this fight by virtue of his superior experience, but I think this is a very winnable bout for Folayang. If he can put Kwon on his back, which I believe he will, then he could ground and pound his way to victory.
Kwon will be looking for the knock out from the second the bell goes but Folayang is also a dangerous striker which makes this a very unpredictable contest. If the fight remains on the feet than either fighter could win with a KO at any moment but if Folayang is successful with his takedowns, I think he will emerge victorious.
I expect this to be a real war of attrition from which neither fighter will emerge unscathed.
