It turns out the knee injury that forced “Shogun” Rua out of UFC Fight Night 117 this coming Saturday, didn’t recently occur.

A couple of days ago the UFC announced that Rua has been forced out of the upcoming card’s headliner, and that Yushin Okami has agreed to step-up on very, very short notice, to fight Ovince Saint Preux. Saturday’s event is taking place in Japan, where, if you’re a longtime MMA fan, you know Rua scored some of his biggest wins to date.

Since it was announced that Rua has had to withdraw from his rematch with OSP, the Brazilian star has released the statement below. In it, “Shogun” reveals that he injured his knee shortly into his training camp (statement via MMA Fighting):

Fighting has been my life for more than 15 years. It’s what I have chosen for myself, and what I love to do. For me it’s really hard to have to step out of a fight, really difficult, and to accept that this was the only viable alternative wasn’t easy at all. Unfortunately, still early in this camp, I injured my knee.

I spent all Camp doing all within my reach to be able to fight on September 23rd, trained the whole time under medication, protection in my knee, ice and physical therapy. I went beyond my limit because fighting in Japan again is something I have been dreaming about for a long time, because I didn’t want to disappoint the fans, and because I was raised this way in martial arts by my master.

I already stepped up to fight injured many times in my career, and there’s wasn’t a lack of effort or trying this time as well. But unfortunately all the effort just ended up aggravating the injuries, and we got to a point where my team and I had to accept that there wasn’t any alternatives anymore and I had to pull out of the fight. It wasn’t easy.I want to apologize to my opponent, I have been in the same situation when we faced each other for the first time and I know it’s never easy, and most of all apologize to the public, specially those who were anxiously waiting for this fight.

I’ll take care of my recovery now, heal my injuries and comeback stronger. Challenges are put in front of us everyday, and what really matter is how we face them.

Thank you all for the support.

Rua was quickly knocked out by OSP when they fought back in 2014. Saturday’s card will be hosted by the Saitama Super Arena.
