Seems pretty criminal to me if it happens:

Wrestling has been dropped from the Olympic Games from 2020 by the International Olympic Committee to make way for a new sport.

The IOC's programme commission assessed each sport's performance at the London Games before making their decision.

But wrestling could enjoy a reprieve as it now joins seven sports hoping to be included in 2020.

A decision on which sport will be added in 2020 will be made when the IOC meet in Buenos Aires in September.

The possible sports in the mix (along with wrestling) for consideration for inclusion? Baseball, Karate, Roller Sports, Sport Climbing, Squash, Wakeboarding, Wushu.
