While 18 fighters took part at Strikeforce: Rousey vs. Kaufman, only the two main eventers were given a drug test. Both Ronda Rousey (6-0) and Sarah Kaufman (15-2) passed. Earlier results came back "invalid." The California State Athletic Commission (CSAC) stated the issue was a clerical error.
"We randomly select people from each of our events, and we always do the main event title fights," said Kathi Burns, CSAC interim executive officer, to MMA Junkie. "But we just didn't select to do any others at that event."
Burns noted that the decision to only test the main event fighters was not due to budgetary issues.
"We don't just test the main event," said Burns. "We definitely always do that, and usually in addition, we'll pick another fight or two on the undercard. Sometimes we do, sometimes we don't. That's kind of the point of doing it randomly enough to where people know it will be done, but won't know exactly when and where it will be done."
