Aside from his refusal to fight the opponent the UFC wanted him to fight, War Machine aka Jon Koppenhaver didn’t exactly ingratiate himself to Joe Silva and the Zuffa brass with his comments on Evan Tanner’s death:

No one is sure yet but it sounds like it was a suicide. Sad thing is that it makes sense. What else is an UNDERPAID fighter supposed to do at the end of his career?
Cash in his 401K? Collect social security? Start to work some shitty job for 10 bucks an hour?
Sh*t ain’t boxing and if you’re not Chuck Liddell or Tito Ortiz you don’t get paid d*ck.
Wasn’t like he made MILLIONS and blew it all like Mike Tyson, this guy fought his entire life and didn’t have sh*t.
No wonder why he took off to the woods. Prolly reminisced on the days when he was champ, the days when growing
old didn’t matter and took his life. Severe depression plagues MANY fighters at the end of their careers. Mark my words
when I say that “HE MAY BE THE FIRST, BUT HE ISN’T THE LAST.

After later reports stated that Tanner’s death most likely was not a suicide “War machine” removed the post,
but told sources:

I still believe in my heart it was a suicide…maybe he didn’t shoot himself in the head, but I think he went up
there maybe with plans not to come back…He was depressed, guaranteed. He had just lost to Kendall [Grove].
He was getting older. He knows he has no retirement plan. He had nothing, dude. That could be the outcome
for a lot of fighters, myself included. I for damn sure guarantee you that if I’m in my 40s and I didn’t make enough
money and I don’t have my own gym to support myself or whatever, I’ll probably kill myself too.
