Rafael dos Anjos will likely put the UFC lightweight title on the line later this year against Donald Cerrone, but "Cowboy" appears to be tired of waiting.
Cerrone, who suffered his last loss in the UFC against dos Anjos in 2013, suggested on Twitter that the UFC lightweight champion, who suffered a knee injury earlier this year, is actually taking a time off to avoid failed drug tests.
"@AustinTAllen: @Cowboycerrone Any news on when you're beating Dos Anjos?" Whenever he cycles off and can pass the blood test

dos Anjos, who never tested positive for illegal substances throughout his MMA career, fired back.
