The Seahawks announced the plan Wednesday, saying the goal is to ensure a safe environment for all fans, including those supporting the visiting team.
The game is a sellout and will be featured on national television Sunday night. With both teams having legitimate Super Bowl aspirations, the game will give the winner an early lead in the NFC West and coaches, players -- and fans -- some bragging rights until the next match-up in San Francisco later this season.
The Seahawks say game day staff will intervene against unruly behavior, foul or abusive language and verbal and physical harassment of opposing team fans or stadium guests and staff members.
Any fans asked to leave for violations of fan conduct will have to complete a four-hour online educational course at their own cost before they will be cleared to attend events at the stadium again.
