The California State Athletic Commission on Monday denied an appeal by former Strikeforce women's featherweight champion Cristiane "Cyborg" Santos to have her one-year suspension reduced.
Santos' license was suspended by the CSAC when her prefight urine sample came back positive for stanozolol metabolites shortly after she defeated Hiroko Yamanaka on Dec. 17.
As a result of Santos' positive drug test, the fight's outcome was changed to a "no contest," she was fined $2,500 and stripped of her 145-pound title.
Santos sat before members of the CSAC on Monday in Sacramento, Calif., in an attempt to have her year-long ban, which was applied retroactively to Dec. 16, cut to six months.
During the hearing Santos admitted the error of her ways.
"I made a mistake," said Santos, who has professional record of 10-1 with one no contest. "I do not condone the use of performance-enhancing drugs in MMA."
