Chael Sonnen has suddenly announced his retirement from the world of mixed martial arts today.  This comes on the heels of word that came out on Tuesday that he had failed a random drug test with the Nevada Athletic Commission back on May 23.

This was Sonnen's retirement statement:

"Right now, guys, I do want to take an opportunity to officially announce my retirement from competitive mixed martial arts.  I want to stay within the rules, and I don't fully understand them.  And I have to put my health first, I have to put my family first.  If I know what I know now, and I know that this is going to work, and I'm going to be able to get my wife pregnant, and look forward to having a family, I'm going to do the exact same thing 20 more times, which is going to put me out of compliance 20 more times.  So, let's just stop with that.  Let me just remove myself.

There's gonna be a day when I am no longer going to have the title of fighter, and that's just a reality Kenny.  But I don't want there to ever be a day where I don't have a title as parent and father and husband and my health has to come first"

Sonnen was a bit combative about the situation regarding TRT when he appeared on Fox Sports 1's "America's Pregame" Tuesday, and mentioned that he would appeal his situation.  That all changed when he appeared on "UFC Tonight" on Wednesday, when he said he would walk away from the sport instead.  He thanked several people, including "the single most important oppoennt" he ever faced in Anderson Silva.

While I am not totally surprised by this, it probably should be this way.  Nevada no longer permits for testosterone replacement therapy, and that creates a bind for those who do use it.  It's saying "if you can't move forward without it, you can't fight."  More fighters have been taking this stance prior to the NAC banning TRT.  Sonnen is in a situation where he feels this is something that he needs to make a family and lead a healthy life.  I can't say that I blame him for taking that stand.  Not to mention that Sonnen's body has reached a point that he can't fight without the TRT therapy, so for him to walk away makes sense.
