Blackzilians founder Glenn Robinson dead

The MMA community lost an influential figure on Thursday.

Glenn Robinson, the founder of the Blackzilians team based out of Boca Raton, Fla., has died due to a suspected heart attack, per MMA Junkie. Robinson’s death was first noted by reporter Christopher James on his Facebook, and later confirmed by Robinson’s daughter Sam via social media.

The Blackzilians team was formed in 2011 as the brainchild of Robinson, who was the president of Iron Bridge Tools, a successful tool manufacturer.
