Ravens safety Tom Zbikowski reportedly has been suspended 45 days by the Chickasaw Nation Boxing Commission for failing a drug test after Saturday's victory in Thackersville, Okla.
His boxing coach, Mike Joyce, told the Chicago Sun-Times they planned to appeal the test result, which they believed was in error. According to Joyce, there will be a new test Tuesday.
According to the Sun-Times, the drug in question is marijuana or, more specifically, THC.
"After the fight, all the fighters tested were positive," Joyce said. "They had you pee in a cup and put a strip of something in there. I've never seen results where you get them the day of the fight. It was like a home pregnancy test or something."
Zbikowski improved to 4-0 as a professional boxer after he won by a first-round technical knockout on Saturday. His next fight was scheduled for June 4 at the Staples Center in Los Angeles.
“He’s taken all sorts of tests for the NFL and he’s never tested positive ... ever,” Joyce told the Sun-Times.
Zbikowski didn't immediately respond to messages from The Sun.
