Strikeforce has lost one of its key players in the light heavyweight division in the form of Rafael “Feijao” Cavalcante who tested positive for a banned substance after a May 19 victory over Mike Kyle. As a result he has been suspended for a year and fined $2,500.

No specific information was offered in terms of the actual drug he tested positive for or if his win will be changed to a No Contest.

News of Cavalcante’s was first reported by MaxBoxing and has since been confirmed by MMAFighting.

The win over Kyle was Cavalcante’s second consecutive instance of in-ring success and was expected to earn him a crack at the company’s vacant divisional championship later this year with Gegard Mousasi his likely opponent. Now, with Cavalcante’s current status, it seems highly unlikely the two will meet at any point given Strikeforce’s business woes.

Cavalcante’s camp has said they will fight the CSAC’s findings, claiming innocence in the matter.
