Kimbo Slice is dead.

via Bellator Press Release.

We are all shocked and saddened by the devastating and untimely loss of Kimbo Slice, a beloved member of the Bellator family. 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.

This is unfortunate.

Everyone will point to steroids or other illegal drug use but I believe its something different.  The guy had a "career" as a street fighter making YouTube videos before he went legit and got into the UFC and later Bellator.

Street fighting is a dangerous thing.  Bruises add up.  So does brain damage... I'm betting his past "career" finally caught up with him.
