George Foreman, the two-time world heavyweight boxing champion and Olympic gold medalist whose legendary rivalry with Muhammad Ali culminated in the famous ‘Rumble in the Jungle’ title bout, died Friday according to a verified social media account dedicated to Foreman.

According to CMG Worldwide, Foreman explained his choice by saying, "The best boxer I ever saw was Joe Louis. No one has surpassed him. Well taught and gifted competitor. There’s never been a boxer better than Joe Louis. You’d take one shot from him and you were sure he’d have seven or eight more coming for you."
