Long time UFC heavyweight competitor Gabriel Gonzaga has confirmed that he has been released from the promotion following his loss to Brendan Schaub at UFC 121.

“Official now – Out of UFC – Thanks for all your support – back to normal life and BJJ forever,” he wrote on twitter.

Gonzaga first appeared in the UFC back at UFC 56 in November of 2005.  In many ways he was lucky to have lasted as long as he has in the UFC given his performance that night against Kevin Jordan in one of the worst fights in the history of the organization.  He redeemed himself with an out-of-the-blue last minute KO victory however and would go on to enjoy a 12 fight career in the promotion, ending up with a 7-5 record.

Along the way Gonzaga produced one of the most famous knockouts in the UFC’s history, putting Mirko Cro Cop to sleep with the Croatian’s own signature move, a head-kick.

That marked his fourth victory in a row inside the octagon and lead to a title fight with Randy Couture which he would lose by TKO.  Since then the Brazilian’s form has never reached the same heights again, suffering clean KO’s at the hands of both Shane Carwin and Junior Dos Santos along the way.

His release comes after back-to-back defeats in 2010.  At the age of 31 there’s still time left in Gonzaga’s career, but at this stage it’s unclear what his next move will be.
