LAUSANNE, Switzerland – IOC leaders dropped wrestling from the Olympic program on Tuesday, a surprise decision that removes one of the oldest Olympic sports from the 2020 Games.

The IOC executive board decided to retain modern pentathlon — the event considered most at risk — and remove wrestling instead from its list of 25 "core sports."

The IOC board acted after reviewing the 26 sports on the current Olympic program. Eliminating one sport allows the International Olympic Committee to add a new sport to the program later this year.
