Redskins tight end Fred Davis has been suspended indefinitely by the NFL for violating the substance abuse policy, a suspension that was initially reported in January for the impending free agent.

Davis was suspended the final four games of the 2011 season for what he said was a failed test for marijuana use. Davis released a statement via the NFL Players Association on Wednesday afternoon claiming that pot had nothing to do with this suspension, which he blamed on unwittingly taking a supplement that included banned substances.

““I would like to clarify the circumstances that resulted in my current suspension. In the past, I made the mistake of knowingly ingesting a banned substance. For over two years, I’ve worked very hard to eliminate marijuana from my life, and I have not had a positive test for it since 2011,” Davis said. “Unfortunately, a couple of months ago I took a supplement that contained a banned substance. I now know that supplements are not regulated by the FDA and may contain banned substances.
