In an effort to weed out unruly fans, the Seattle Seahawks say they will have undercover police officers wearing opposing team apparel beginning with Sunday night's highly anticipated matchup against the San Francisco 49ers.
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 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.
