The MMA community was taken aback on Monday when news surfaced that UFC 183 headliners Anderson Silva and Nick Diaz, who met Saturday at Las Vegas’ MGM Grand Garden Arena, both failed drug tests.

Silva (36-4 MMA, 17-2 UFC) was flagged for Androsterone and Drostanolone metabolites stemming from a random pre-fight test. Diaz’s (26-10 MMA, 7-7 UFC) post-fight test showed marijuana metabolites.

While more details regarding the tests and what kind of punishment both fighters will face are still forthcoming, that didn’t prevent fans, fighters and more from rushing to social media to comment on the situation.

Check below for the top Twitter reactions to Silva and Diaz’s failed UFC 183 drug tests.

More disappointment in #mma 😔😒 — Kenny Florian (@kennyflorian) February 4, 2015

All fighters should follow the rules if they wanna be a pro-fighter but #PED's = way worse than prescribed or recreational marijuana use. — Kenny Florian (@kennyflorian) February 4, 2015

Cheating is rampant in every facet of humanity and therefore EVERY FORM of major sporting. Mans perpetual search to get the edge. — Chris Wade (@CWadeMMA) February 4, 2015

Disgusted at the state of MMA. Coke, PED's, poor match making, Reebok situation and over saturation. The sport is in huge trouble. — Dan Sammit (@GtaMMACoach) February 4, 2015

I'm not shocked silva took some PEDs coming back from that leg break but it makes mma as a whole look bad since he's been the face of it — roland delorme (@rolanddelorme1) February 4, 2015

Oof — Stipe Miocic (@stipemiocicufc) February 4, 2015

Anderson Silva popped for steroids? There goes that GOAT label….. — Todd Grisham (@GrishamESPN) February 4, 2015

What's the big deal with the failed drug tests, they'll just go to rehab for the night and it will just kinda go away right? — Vinc Pichel (@FromHellPichel) February 4, 2015

I'm going to let you guys all in on a little secret. EVERY SINGLE PROFESSIONAL ATHLETE IN EVERY SINGLE SPORT TAKES STEROIDS. You're welcome — Sean McCorkle (@BigSexyMcCorkle) February 4, 2015

We're Silva's test results known by the commission and UFC before the fight? If so, why was he allowed to compete? — TJ Grant (@TJ_Grant) February 4, 2015

Well, Diaz just pretty much cemented his legacy. Silva put his in a shredder. — Dann Stupp (@DannStupp) February 4, 2015

Do i agree with Silva taking PEDs? No! but from GOAT to derailed then broken leg i can understand when the pressures have led him astray — Andy Ogle (@thelittleaxe) February 4, 2015

Sad that Anderson silva tested positive for steroids. Although in hindsight, I'm not surprised. I'm too naive. #any1notcheatingbesidesme — michael (@bisping) February 4, 2015

I will still be a fan of Anderson just because he used a PED doesn't discount all the hard work he put in or the kind of talent he's has — ike vallie-flagg (@IKEVF) February 4, 2015

A fighter has now tested positive for a drug in UFC 181, UFC 182 & UFC 183. — Darren Rovell (@darrenrovell) February 4, 2015

Only thing I am testing positive for is Pasta or Cheese. — Joe Lauzon (@JoeLauzon) February 4, 2015

All is lost. I’m gonna go jump off a fu king bridge. ANDERSON SILVA DOES NOT USE PEDs!😕 — Marcelino Evil (@KCBanditMMA) February 4, 2015

I know guys who would swear on their mother that they've never done PEDs. You open their refrigerator and its full of vials and syringes. — Mac Danzig (@macdanzigmma) February 4, 2015

A guy has super miraculous recovery from an injury and people are surprised that he had steroids in his system? — ike vallie-flagg (@IKEVF) February 4, 2015

Come on now Anderson… Plead innocent for 1 steroid maybe but plead innocent for 2 types of steroids. I don't like your odds — Will Brooks (@illwillbrooks86) February 4, 2015

Wow. GSP is so smart. I have so much respect for the way he fooled everyone. Also an absolute legend. — caposa (@GrabakaHitman) February 4, 2015

Someone once told me "If you're in the top 10 in UFC you're on something!" Looks more and more true with every major fight. Sad to hear. — Anthony Birchak (@abirchakMMA) February 4, 2015

Spiderbolics — C H I T O V E R A (@chitoveraMMA) February 4, 2015

If you're found with anabolic steroids in your system weeks before your fight you should NOT be allowed fight and should be banned. — Coach Kavanagh (@John_Kavanagh) February 4, 2015

If it's illegal then it's illegal. End of. BUT an opponent on weed is less dangerous than opponent on steroids and ban should reflect this. — Coach Kavanagh (@John_Kavanagh) February 4, 2015

Maybe since @nickdiaz209 will be suspended at length he would be open to coming to Asia and fighting under real MMA rules. @ONEFCMMA — Ben Askren (@Benaskren) February 4, 2015

Wow just found out how to be the GOAT & get paid @ufc that why he likes Nike just do it! Lol it's funny http://t.co/1sqQHdrQWF — Roy Nelson (@roynelsonmma) February 4, 2015

“@alliseeisgold: Does anyone in the UFC actually follow the rules?” Few of us still out there, I know I can vouch for myself n teammates — Benson Henderson (@BensonHenderson) February 4, 2015

Why is everyone's mind blown by Anderson on the needle? When was the last time a man broke his leg & magically healed in record time. — Bigslow (@LukeBarnatt) February 4, 2015

I have said that there is a major problem in our sport. It breaks my heart that the greatest of all times succumbed to the pressure. #PED — Tim Kennedy (@TimKennedyMMA) February 4, 2015
