Kimbo -- real name Kevin Ferguson
"One of the most popular MMA fighters ever, Kimbo was a charismatic, larger-than-life personality that transcended the sport."
"Outside of the cage he was a friendly, gentle giant and a devoted family man. HIs loss leaves us all with extremely heavy hearts, and our thoughts and prayers are with the entire Ferguson family and all of Kimbo's friends, fans and teammates."
