SEATTLE - Seattle Seahawks CB Richard Sherman says there was a chain of custody mistake made in the handling of his positive test that was the basis for appeal heard on Friday.

Sherman missed practice the last two days of the week in order to attend the hearing for his appeal in front of the league. Adam Schefter of ESPN reported early Sunday that Sherman's case claimed that the cup used to collect his urine was broken and required non-sealed cup to be placed underneath to prevent leaking.

Sherman didn't specifically confirm that was the argument but did say after the game there were mistakes made in the process.

"It should go well," Sherman said. "There was a chain of custody mistake. There was mistakes made by the tester. The league’s argument was they’re allowed to make mistakes and they’re allowed to break the rules and they can get away with it. It’s up to them. The appeal officer is paid by the league so if he goes their way, that’s what it is. It’s not an even playing field in that appeal room."

Sherman said he didn't know when to expect the ruling to be made by the league. He also said he would pursue the case further if the option is available.

"I wish I could," Sherman said. "I don’t know if it’s possible. If I could pursue it further, because I’d win in a neutral court, but I don’t know if I can pursue it further."

Even if Sherman does get suspended this week and is forced to miss the next four games, he's not going to let it affect him. Growing up in Compton, Calif., he's been through more challenging situations then the one currently in front of him.

"I’m from the inner city," Sherman said. "I’m from a bad place and adversity is something you always have in your life and you just got to meet that adversity head on and I’ve done it my whole life and this is just another opportunity."

Sherman had a 90-yard return for a touchdown off a blocked field goal early in the second quarter and an interception of San Francisco 49ers QB Colin Kaepernick in the Seahawks 42-13 dismantling of the 49ers on Sunday night.
