Mixed martial artist Kimbo Slice died Monday at age 42, reports MMAFighting.com’s Marc Raimondi.

The cause of Slice’s death has not yet been publicly disclosed.

“We are all shocked and saddened by the devastating untimely loss of Kimbo Slice, a beloved member of the Bellator family,” Bellator CEO Scott Coker said in a statement.

TMZ first reported Monday that Slice had been taken to Northwest Medical Center near his residence in Coral Springs, Fla., and that his condition was “dire.”

Slice won his last Bellator bout in February, which was a three-round decision against Dhafir “Dada 5000” Harris, but later had the victory changed to a no-contest after he tested positive for steroids. He was scheduled to headline Bellator 158 in July against James Thompson.
