Kimbo Slice, Ken Shamrock both tested positive for steroids

We already knew that Kimbo Slice and Ken Shamrock failed their pre-fight drug tests at Bellator 149 in Houston last month, but now we know what substances both were on.

MMA Fighting reports that both Slice and Shamrock tested positive for steroids. Slice tested positive for nandrolone and had elevated testosterone levels. Shamrock also tested positive for nandrolone and methadone, and he also had an elevated testosterone level.

Results of the failed drug tests were learned via a records request through Texas’ Licensing and Regulation department.

Kimbo won his Feb. 19 fight against Dada 5000, but the outcome was overturned to a no contest given Kimbo’s positive test. Dada 5000 cut 40 pounds to make weight for the fight and had severe health issues such as dehydration, which led in part to his third-round TKO defeat.

Shamrock lost to Royce Gracie by first-round TKO. He also tested positive for steroids following a 2009 fight.
