Richard Sherman announced on Twitter that he has won his appeal against the NFL in regards to a positive performance enhancing drug test.

Sherman, cornerback of the Seattle Seahawks, has been facing a four-game ban.

Richard Sherman argued that his urine specimen that tested positive for performance enhancing drugs had been contaminated, according to a source.

Sherman is appealing a four-game suspension by the NFL.

Sherman claims that the cup containing his urine specimen was leaking, prompting the collector to place a second cup underneath it to capture any leakage, the source said.

A decision is expected to be made in the coming week.

Richard Sherman missed the Seattle Seahawks' practices on Thursday and Friday to be present at his appeals in New York City.

Sherman faces a four-game suspension for a violation of the NFL's performance enhancing policy.

The Seahawks don't expect a ruling on Sherman until next week and that he will play on Sunday against the 49ers.

Gregg Williams has yet to officially begin the process of being reinstated by the NFL, but is expected to soon.

Williams' future with the St. Louis Rams remains uncertain. Williams is signed with the franchise through 2014, but they have remained secretive of their plans for him.

Williams may have difficulty securing employment with another team due to his actions and testimony to the NFL.

Paul Tagliabue overturned the suspensions of four current and former players of the New Orleans Saints.

Tagliabue found that three of the players engaged in conduct detrimental to the league, but stressed that the Saints' coaches were very much involved.

"Unlike Saints' broad organizational misconduct, player appeals involve sharply focused issues of alleged individual player misconduct in several different aspects," said a portion of ruling released by the NFL. "My affirmation of Commissioner Goodell's findings could certainly justify the issuance of fines. However, this entire case has been contaminated by the coaches and others in the Saints' organization."

Scott Fujita was the only player cleared of conduct detrimental to the league by Tagliabue.

The NFL said Tuesday afternoon that it respected Tagliabue's decision. 

"We respect Mr. Tagliabue's decision, which underscores the due process afforded players in NFL disciplinary matters. This matter has now been reviewed by Commissioner Goodell, two CBA grievance arbitrators, the CBA Appeals Panel, and Mr. Tagliabue as Commissioner Goodell's designated appeals officer. 

"The decisions have made clear that the Saints operated a bounty program in violation of league rules for three years, that the program endangered player safety, and that the commissioner has the authority under the CBA to impose discipline for those actions as conduct detrimental to the league."

Brandon Jacobs was suspended by the San Francisco 49ers for the remainder of the regular season.

Jacobs intends to file a grievance against the 49ers.

Jacobs earns $55,000 per game.

Jacobs criticized the 49ers on Saturday on Twitter.

Brandon Browner is expected to begin his four-game suspension for violating the NFL's performance enhancing drug policy this week.

Browner is a starting cornerback for the Seahawks.

Richard Sherman's appeal hearing is scheduled for Dec. 14.

Cedric Griffin has been suspended four games by the NFL for testing positive for performance enhancing drugs.

Griffin joined the Washington Redskins this season at cornerback.
