Seattle Seahawks cornerback Brandon Browner will miss the rest of the regular season after being slapped with a doping ban, the NFL said Wednesday. Browner, who was named to last year\'s Pro Bowl after registering six interceptions and 54 tackles in 2011, was hit with a four-game suspension for violating the league\'s policy on performance-enhancing substances. The 28-year-old former CFL standout tested positive last month for the prohibited stimulant Adderall, NFL.com reported. The suspension comes at a key time for the Seahawks, who at 7-5 are battling for an NFC post-season berth. They currently hold the conference\'s second wild card spot and trail NFC West leader San Francisco by 1 1/2 games. Browner has intercepted three passes, recorded 44 tackles and forced three fumbles in the present campaign.
