Chael Sonnen's positive random drug test shook the MMA world Tuesday afternoon, and knocked the controversial fighter out of UFC 175. He plans to appeal the ruling.

Check out how his fellow fighters reacted below.

I'm all for random drug test, yeah it shuffles deck on fight cards but helps clean up the sport & protects fighters in already violent sport — Ulysses Gomez (@uselessgomez) June 10, 2014

Wahhh, wahhh! All the pro athletes keep getting caught juicing, big whoop! Priests get caught raping, that's a bigger problem. — War Machine (@WarMachine170) June 10, 2014

It's pathetic to see ALL these guys failing these "random" drug tests. The majority of guys are using. With random tests you would see it. — Tim Kennedy (@TimKennedyMMA) June 10, 2014

Well Chael Sonnen does rhyme with Fail Sonnen ... — Derek Brunson (@DerekBrunsonMMA) June 10, 2014

One can't just come off of #TRT & be ready to compete. Isn't as easy of a process as people think. Medically ambitious expectation. — Kenny Florian (@kennyflorian) June 10, 2014

My toe is still broken. I haven't stepped foot inside AKA since my fight. I'm not crazy I can't fight in 3 weeks as much as I would like to. — Luke Rockhold (@LukeRockhold) June 10, 2014

Will Vitor even pass his test that is the question? — Luke Rockhold (@LukeRockhold) June 10, 2014

Let's just make two leagues. The juice heads who need PEDs and then the real athletes who just work hard without any PEDs. That's fair — Cody Bollinger (@CodyBollinger) June 10, 2014
