Cornerback Brandon Browner will miss the final four regular-season games to serve a suspension for violating the NFL's policy on performance-enhancing drugs. Browner is expected to miss Sunday's game against the Arizona Cardinals as he begins serving a ban for reportedly testing positive for Adderall, according to the Seattle Times. Richard Sherman, the Seahawks' other starting cornerback, is appealing the NFL's decision to suspend him four games for an alleged PED violation. His appeal is scheduled for Dec. 14. Browner is a former CFL standout who signed with the Seahawks last season and was named to the Pro Bowl.
