Nicky Ryan is in at -66kg due to Justin Rader pulling out. The three-time ADCC veteran became sick on Wednesday September 20 and had to withdraw. 16-year-old Ryan, who took bronze at both recent North American Trials (East and West Coast) becomes the youngest male in history to compete in ADCC.
Jackson Sousa replaces Checkmat teammate Luiz Panza at -99kg, with the South American Trials winner pulling out due to a foot injury.
Sergio Ardila, brother of -99kg competitor Paul, will take the spot opened up by the withdrawal of Gilbert 'Durinho' Burns at -77kg.
