Cris Cyborg must pass a random drug test before being allowed to compete at Invicta FC 11.

California State Athletic Commission executive director Andy Foster told MMAFighting.com that Cris "Cyborg" Justino was given a urine test Thursday morning as part of her process to get licensed to compete in the state. Foster expects the results to come back on or around Feb. 24. Justino's main event bout against Charmaine Tweet is scheduled for Feb. 27 at the Shrine Auditorium in Los Angeles.

Justino, 29, has already tested positive for performance-enhancing drugs once in California, after a Strikeforce bout in 2011, which is why she needs to reapply for a license. Justino's urine will be run through every panel, including for recreational drugs. Because this is a condition of licensure, "Cyborg" will need to be clear of everything. She will have to pay for the test out of her own pocket as part of the licensure process.

"She will not be licensed until she satisfies our drug-testing and medical requirements," Foster said.

Justino (12-1, 1 NC) is regarded as one of the best women's fighters in the world. She is currently in negotiations with the UFC, which could lead to a much-anticipated showdown with UFC women's bantamweight champion Ronda Rousey. The two have gone back and forth in interviews and on social media for years with Rousey's biggest gripe being Justino's performance-enhancing drug past.

"Cyborg," the current Invicta women's featherweight champion and former Strikeforce women's featherweight titleholder, had her 16-second TKO win over Hiroko Yamanaka overturned into a no contest when she tested positive for anabolic steroid stanozolol at Strikeforce: Melendez vs. Masvidal on Dec. 17, 2011. Justino was also stripped for her belt at that point.

Justino has fought in MMA just twice since then, beating Fiona Muxlow and Marloes Coenen, each via TKO, in Invicta. Overall, "Cyborg" has not lost since her MMA debut in 2005 in her native Brazil.

Rousey competes one day after Justino-Tweet bout against Cat Zingano at UFC 184 on Feb. 28, also in Los Angeles. As MMAFighting.com reported Wednesday, Rousey and Zingano also have each undergone a random, out-of-competition drug test this week.
