Eva Marie's WWE wellness policy violation is reportedly for Adderall.
The 'Total Divas' star - whose real name is Natalie Coyle - has been banned for 30 days but insists she has a prescription for the medication and will appeal.
She told TMZ: "I am disappointed that this suspension has occurred, yet understand and respect that WWE upholds their Wellness Policy to the letter and won't compromise on its integrity.
"I violated policy by not turning in portions of required paperwork in the time frame WWE Medical deemed timely. I look forward to my return!"
The WWE implemented its Talent Wellness Program in 2006 and it includes substance abuse and drug testing, cardiovascular testing, ImPACT, testing for brain function, annual physicals and health care referrals.
All wrestlers are required to disclose all medication to WWE officials but Eva reportedly did not do so.
This is her first violation.
She had been scheduled to compete at SummerSlam, teaming with Natalya and Alexa Bliss against Becky Lynch, Naomi, and Carmella, but the ban means she won't be able to participate in the match.
The news of Eva Marie's ban came one day after it was announced Alberto Del Rio and Paige have been suspended for also violating the company's talent wellness policy.
The couple - whose real names are Saraya-Jade Bevis and Jose Rodriguez - also received a 30-day ban.
The WWE said in a statement: "WWE has suspended Saraya-Jade Bevis (Paige) and Jose Rodriguez (Alberto Del Rio) each for 30 days effective tomorrow, August 18, for a first violation of the company's talent wellness policy."
And in June, WWE superstar Roman Reigns was suspended for the same reason, receiving an equal punishment.
In light of the decision, Roman subsequently took to Twitter to issue an apology to his friends and family, as well as his fans in the WWE.
He wrote: "I apologize to my family, friends and fans for my mistake in violating WWE's wellness policy. No excuses. I own it. (sic)"
