The Seahawks' Brandon Browner and Richard Sherman each might face four-game suspensions for violating the league's policy on performance-enhancingsubstances.

ESPN's Adam Schefter reported on the possible suspensions, citing unnamed league sources.

That punishment is being appealed, according to Schefter.

A report on NFL.com reported a source said both players were accused of taking Adderall, which is a combination of dextroamphetamine and amphetamine used to fight attention deficit disorder.

Both players would likely be available for the game next week at Chicago if the punishment is being appealed as reported.

Neither the NFL or the Seahawks have not commented on the report.
