The Texas Department of Licensing and Regulation has placed Slice and Shamrock on administrative suspensions pending an adjudication process, the report says. The maximum penalty for fighters who fail drug tests in Texas is a 90-day suspension and $5,000 fine.
Slice, 42, defeated Dhafir "Dada 5000" Harris in Bellator 149 by third-round TKO in a widely criticized fight. The two heavyweights were clearly fatigued in the first round. The comical fight had serious implications however as Harris suffered cardiac arrest after the fight and had to be resuscitated. He was released from the hospital last week.
Royce Gracie defeated Shamrock by controversial first-round TKO.It's not the first time Shamrock, 52, has failed a drug test. In 2009, after a win over Ross Clifton, three steroids were found in his system: norandrosterone, noretiocholanolone and stanozolol, the report says.
