All Strikeforce Challengers 17 Drug Screens Come Back Clean

All Strikeforce “Challengers 17” drug screens have come back negative, the Nevada State Athletic Commission announced Friday.

Twelve fighters in total were tested following their performances on July 22 at the Palms Casino Resort in Las Vegas, including headliners Bobby Voelker and Roger Bowling. Additionally, Shawn Jordan, Devin Cole, Ovince St. Preux, Joe Cason, Anthony Smith, Bill Cooper, Sterling Ford, Sarah Kaufman, Adlan Amagov and T.J. Cook were also tested and cleared.

All competitors tested were screened for both performance enhancing drugs and drugs of abuse such as marijuana and cocaine. Challengers 17 aired live on cable network Showtime.

Voelker knocked out Bowling in the second round of their welterweight headliner, earning him the deciding victory in their fight trilogy. Also notable was another dominant performance from light heavyweight St. Preux, as the former University of Tennessee linebacker quickly pounded out Cason in just 72 seconds. Additionally, Sarah Kaufman made a statement in her one-sided victory over Liz Carmouche, outpointing the “Girl-Rilla” to cruise to a unanimous nod.
