Ken Anderson was released from TNA Wrestling after he failed a drug test … and multiple backstage sources tell us it was given to him after he appeared to be under the influence during a match.

Sources with knowledge of the situation tell us the match against Eric Young was supposed to air on January 19th, but Anderson looked so bad in the ring they had to remove it from the show.

We’re told he was immediately forced to take a drug test backstage, then sent home.

As we previously reported, Ken recently proclaimed “F**K TNA” at an ICW show while announcing he was no longer with the company.

Pro Wrestling Sheet attempted to reach Anderson for comment. So far, no word back.

We also attempted to reach TNA officials for comment. No word back either, but sources tell us management is hoping Ken gets some sort of treatment.
