One of Invicta's brightest young stars is facing a ban.

Andrea Lee, a top Invicta FC flyweight, tested positive for a banned diuretic and has been hit with a temporary suspension by the Nevada Athletic Commission, MMA Fighting confirmed with NAC executive director Bob Bennett on Thursday.

Bennett said that Lee's urine test in relation to Invicta FC 16 on March 11 in Las Vegas came back positive for the substance canrenone and/or spironolactone.

Lee broke the news herself on social media.

"I have not taken any drugs or any supplements that will help enhance my performance, so do not get your facts wrong!" Lee wrote.

On Twitter, Lee did admit to taking a "fluid pill."

Lee (4-2) will have a disciplinary hearing in front of the NAC at a later date. She lost her fight against Sarah D'Alelio via third-round submission at Invicta 16.

Lee, 27, also competes for Legacy FC and Legacy Kickboxing. The Louisiana native, nicknamed "KGB," had won two MMA fights in a row heading into the bout with D'Alelio.

Invicta released a statement later Thursday evening. Here is the text:

Invicta FC will fully cooperate with the NAC on the matter and supports Lee's right to due process. Invicta FC consistently informs its athletes about established policies and expectations in regard to conduct, including the strictly prohibited use of performance enhancing drugs, stimulants and masking agents. This positive test represents a violation of those policies.

The new NAC guidelines for drug-test failures, voted on last year, state that a first-time offender for diuretics should get a two-year suspension and a fine of up to 40 percent of his or her purse.

UFC women's bantamweight fighter Ashlee Evans-Smith tested positive for diuretics in Nevada last year and was suspended for nine months.

Update: Invicta issued the following statement concerning Lee.
