The event itself is still far away, but some fights are already being announced.
The ADCC commission has just announced that the 2015 edition will feature a master superfight between Jose Mario Sperry and Ricardo Liborio.
Sperry competed in the last two editions and defeated Renzo Gracie in 2011 (Notingham) and Fabio Gurgel in 2013 (Beijing).
Here is the video of his fight against Gurgel.
Liborio is one of the founders of American Top Team and also an ADCC veteran.
In 1999, Liborio finished third in the 88kg division and in 2000 he secured a silver medal in the same division.
Here’s a video of him competing at the ADCC 2001.
