Five fighters, including both who competed in the main event, were tested for performance enhancing drugs following Strikeforce: Marquardt vs. Saffiedine. All five passed the tests, which also looked for recreational drugs and steroids.
Tarec Saffiedine, Nate Marquardt, Josh Barnett, Tim Kennedy and Kurt Holobaugh were all tested by the Oklahoma Athletic Commission.
The card was the final one for Strikeforce, which has now closed up shop following a lengthy run. Four of the five tested fighters have already signed with the UFC, with Barnett being the lone holdout so far.
