The 2009 Abu Dhabi Combat Club (ADCC) grappling competition got underway today (Sept. 26) in Barcelona, Spain, wrapping up the quarterfinal brackets as well as a much ballyhooed superfight that saw Ronaldo "Jacaré" Souza overcome the venerable Robert Drysdale.

Former Ultimate Fighter (TUF) 8 contestant Vinícius Magalhães breezed through the quarterfinals (via slick flying armbar), as did former UFC and current Strikeforce heavyweight Fabricio Werdum.

Also making the cut was staunch mixed martial arts veteran Jeff "The Snowman" Monson, female fightmonger Cristiane "Cyborg" Santos and ex-WEC competitor Glover Teixeira.

Taking an early exit was fading mat technicians Ricco Rodriguez, Dean Lister and Márcio "Pe de Pano" Cruz along with Megumi "Mega Megu" Fuji and Kron Gracie.

ADCC is an invitation-only event held every two years to determine the world’s best no-gi grapplers. Only 16 competitors in each of five weight classes plus the "absolutes" are selected, and it is widely considered the most difficult submission fighting event to qualify for.

Be sure to check back tomorrow for the remaining results and highlights from this year's tournament.
