WWE.com has announced that Roman Reigns (real name Joe Anoa`i) has been suspended for 30 days for failing a Wellness test – his first violation since being under contract with the company.

WWE do not name the specific substance or reason for test failures, it could be anything from marijuana to steroids. Reigns addressed the situation in a Tweet:

I apologize to my family, friends and fans for my mistake in violating WWE’s wellness policy. No excuses. I own it.

— Roman Reigns (@WWERomanReigns) June 21, 2016

The company have not made any announcements regarding the WWE World Heavyweight Championship match, but he’ll be back just in time for Battleground anyway. He’s set to face Dean Ambrose and Seth Rollins in a Triple Threat. This may be why Ambrose got the belt.
