UPDATE: Seattle Seahawks cornerback Richard Sherman tweeted Thursday afternoon that he won the appeal for his test of performance enhancing drugs. Sherman was at risk of being suspended for four games if he had lost the case. The NFL also tweeted the news on Thursday.
News first broke of his failed test Nov. 28. Sherman's argument was that the cup was leaking at the time that he submitted it and that there were mistakes made by the tester at the lab. Sherman said a second cup was placed under his cup to stop the leaking and the seal on that second cup was broken. His drug test for Adderall will now be voided because it has broken the chain of custody and Sherman will not be suspended.
Sherman, 24, tweeted his thoughts on Christmas about the reputation of the drug tester, claiming that the person who conducted his test has a "history of errors."
Sherman had said before he declared victory that if the drug tests come back positive, he would still continue his appeal and would sue the league:
"I can't get back playing regardless. I can just sue the league, and that's probably what I'm going to do if they suspend me."
The Seahawks' other cornerback, Brandon Browner, is already serving a four game suspension and won't return until the playoffs. Browner opted not to appeal the results of his test for PEDs.
The Seahawks clinched a playoff berth with a 42-13 route of the San Francisco 49ers on Dec. 23, with Sherman returning a blocked field goal attempt for a touchdown and playing an overall pivotal role in the game as the team now readies for the post-season.
