Didn't this happen... Like 2 years ago? 
Kevin seems much more respectful than yager however
Casey's decline in the fight happened so sudden. He said at the hospital they diagnosed him with acute renal failure. Looks like he may need to change some stuff up in the future. 
Bubba said,
If that's true it's the second time he's had kidney failure in a fight. No shame in not responding to the bell. That's pretty hardcore.
If he quit from being tired that's one thing, but if he really did have kidney failure, then that's totally different than quitting from exhaustion.
Renal failure is damn serious and can have lifelong consequences.
They train together. Just sayin...
Kevin isn't a thief
CaliKush -Kevin isn't a thief
Some might say he stole his black belt the first time around (and stole from anyone he profited from by doing so)
Old Thrashbarg -Vader03 - Kevin seems much more respectful than yager howeverExactly. Yager was a toolbag and a half.
I'm sure that what Rickson said when Kevin promoted himself to black belt.
Not even close......
Kidney failure? More like budo failure. He broke and didn't want no more. Haha shit, wasn't his rap song "no surrender" or something? That's gotta suck.
No.
The first thing I think of when I hear Yager is guaranteed repetitive sloppy high kicks and quitting.

@kevinkocasey: Fans don't see what goes on behind the scene, I was admitted to the hospital and was diagnosed with acute renal failure. Care to look it up.
He tweeted this yesterday.
