Warrior One MMA (W-1) has signed Antonio Carvalho to an exclusive multi-fight contract.

Carvalho will be making his comeback at W-1 Bad Blood on March 20th in Montreal following a devastating shoulder injury.

The native of Toronto is a world class fighter who holds a Brazilian Jiu-Jitsu black belt and is one of the few fighters in the world to beat the legendary Hatsu Hioki.

An experienced mixed martial artist, Carvalho has fought in Shooto, TKO and MFC.  With the recent signings of Denis Kang, Vernon White and Chris Clements, and a highly competitive 145 lbs weight division, W-1 was an obvious choice for Carvalho to make his way back to the top.

W-1 Bad Blood will be live at the Pierre Charbonneau Centre in Montreal, Quebec Canada on March 20th, 2010.
