A special meeting was held by the ADCC Committee to select a replacement for Roger Gracie for the Superfight in ADCC 2009. The ADCC Committee considered many top names for the position and after careful consideration they selected Ronaldo “Jacare” Souza for face Robert Drysdale.
Everyone is excited to have “Jacare” compete in Barcelona and the prospects of a very exciting action packed fight have just gone of the scale
Congratulations to Ronaldo “Jacare” and to Robert for having such a worthy opponent!
When contacted about the replacement, Drysdale stated: “I am stoked to be fighting “Jacare”, he is a super aggressive fighter and I look forward to a great fight!”
Jacare: “I can’t wait to show the World how hard I’ve been training for MMA and Grappling. My last fight was disappointing with a result I didn’t expect. I can’t wait to show the World that Jacare is still a force in Submission Grappling!”
