The IBJJF decided to alter the names of the master & senior divisions in its tournaments next year.
From 2014 on, no division will be named senior.
With that, the names now are:
Master becomes Master 1
Senior 1 becomes Master 2
Senior 2 becomes Master 3
Senior 3 becomes Master 4
Senior 4 becomes Master 5
Senior 5 becomes Master 6
