The sudden passing of Kevin “Kimbo Slice” Ferguson shocked members of the fight community, regardless of promotion.

The Bellator and UFC veteran died suddenly at 42, leaving behind six children. MMAjunkie spoke with fighters from both promotions about what it meant to say goodbye to the bearded brawler.

The support was unanimous, and while Slice was marketed as a street thug, it’s evident those who knew him best had an entirely different idea of his true personality.

One of the most widely known fighters in the world, Ferguson was hospitalized three days prior to reports saying he was in “dire” health condition. He subsequently was diagnosed with a liver mass and congestive heart failure, and doctors advised his family a heart transplant was necessary.

At the time of his death, he was scheduled to rematch James Thompson at Bellator 158 on July 16 in London. Their first bout in 2008 broke ratings records and ended in a controversial TKO win for Ferguson after Thompson won most of the bout.

Spike debuts a new documentary, “Kimbo Slice: One of A Kind,” tonight at 7 p.m. ET. The special will lead into “Bellator 157: Dynamite 2” event, which takes place at Scottrade Center in St. Louis.
