Silva bounced back from his latest loss to Cheick Kongo by becoming the King of Pancrase after a 2nd round TKO win over Tatsuya Mizuno. He won this vacated title at Pancrase Rising 6 last 30 May 2007. He was scheduled to defend the championship against the former champion, Kestutis “Tiger” Arbocius, on 14 October 2007 at the Differ Ariake Arena in Tokyo, Japan, but Arbocius no-showed at the event. Shortly thereafter, Silva vacated the Championship to pursue a contract with the newly-formed Hardcore Fighting Championships in Canada. However, the organization folded before he was able to fight once under their banner.
Silva made his professional boxing debut on June 21, 2008 in his native Curitiba, Brazil, knocking out Adriano Vicente in 38 seconds of the 1st round.
