Former Ultimate Fighting Championship (UFC) light heavyweight champion, Mauricio Rua, was forced to withdraw from his UFC Fight Night 117 main event rematch against Ovince Saint Preux, scheduled for this Friday night (Sept. 22, 2017) in Saitama, Japan.

“Shogun” suffered a debilitating knee injury and could not work through the pain, according to comments the Brazilian made on social media. But that shouldn’t come as a surprise to anyone in mixed martial arts (MMA), considering the injuries that have plagued Rua over the past several years.

From his official Instagram page:

Fighting has been my life for over 15 years. It’s what I chose for myself and what I love to do. For me it’s very hard to pull out of a fight, very hard, and accepting that was the only viable alternative wasn’t easy at all. Unfortunately, early in this camp, I hurt my knee. I spent the entire camp doing everything in my power so I could fight on September 23 (22 in Brazil), and I trained the entire time under medicine, protection in my knee, ice and physical therapy. I went beyond my limit because fighting in Japan again is something I’d been dreaming of for a long time, because I didn’t want to let the fans down, and because that’s how I was raised in martial arts by my master

I’ve stepped up to fight injured multiple times in my career, and it wasn’t for lack of effort or trying. But, unfortunately, all this effort ended up making the injuries worse, and there came a time when my team and I had to accept there were no alternatives, and I had to pull out of the fight. It wasn’t easy. I’d like to apologize to my opponent I’ve been in the same situation, including when we fought the first time, and I knew it’s never easy. And, mainly, apologize to the fans, especially those who were anxiously awaiting this fight. I will take care of my recovery now, heal my injuries and come back stronger. Challenges are put in front of us every day, and what really matters is how we face them. Thank you all for the kindness.

Thiago Alves should take notes.

After Rua was benched, the promotion asked hometown hero and former UFC middleweight No. 1 contender Yushin Okami to step in on short notice, which keeps “OSP” atop the Friday night headliner.
