The IOC is considering dropping Wrestling from the 2020 Games.

IMO this would be sad news indeed if it happened as I consider Wrestling to the one Olympic Sport that is the closest to practical fighting/self defence. Wrestling was first introduced into the Olympics 2721 years ago in 708BCE!! (although it wasn't until the late 17th/early 18th Century that modern Wrestling came about, introducing restrictive rules to make it more sportslike (e.g. no punching, kicking, elbowing, kneeing, headbutting or any kind of striking, no holds below the waist etc.) I've sparred against Judo, Taekwondo, Fencing and Wrestling, and I've personally found Wrestlers to be the most formidable opponents.
