Recall that Chen lost to Holloway by knockout on August 26 at UFC Fight Night 225 in Kallang, Singapore. After the fight, the South Korean announced his retirement.
“At the moment when Max helped me get up after the knockout, I already clearly understood that it was time to finish. I don't think I have a technical problem, and in terms of physical ability, I'm better than ever. But those blows that I missed were not supposed to shake me or drop me. And yet, he managed to shake me in the first, second, and then knocked me out in the third round.
So even in the middle of the fight with Max, I thought that I could no longer take the blows the way I used to, ”Zombie MMA Mania quotes.
