Wrestling officials called Tuesday's decision to drop the sport from the Olympic program an "aberration" against a founding event.

Known by its French initials FILA, the sport's governing body said it was "greatly astonished" by the IOC executive board decision.

Past and present Olympic champions in Greco-Roman and freestyle wrestling called the rejection "mind-boggling" and a "tragedy" for the sport.

"FILA will take all necessary measures to convince the IOC Executive Board and IOC members of the aberration of such decision against one of the founding sports of the ancient and modern Olympic Games," said FILA, which is based near the Olympic home city of Lausanne.
