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.
