RENTON, Wash. (CBS Seattle/AP) — The Seattle Seahawks announced that the organization has hired undercover cops to wear San Francisco 49ers gear and patrol Sunday’s game in order to curb unruly behavior.

“We have great fans,” said Seahawks president Peter McLoughlin. “Our goal is to ensure a safe environment for all in attendance, including visiting team fans.”

The Seahawks announced Wednesday they will have the undercover police officers wearing opposing team apparel beginning with Sunday night’s highly anticipated matchup, 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.

The use of tobacco, smoking and the failure to follow instructions from stadium personnel were all included in the press releases’ forbidden activities.

From the press release:

“Similar to last season, fans who have been asked to leave the stadium for violations of the Seahawks Fan Code of Conduct will be required to complete a four hour online educational course focused on fan behavior before they are allowed to return to the stadium. Fans will be responsible for the $75 cost of the course. The team will inform the fan once they have been cleared to attend events at the stadium. If a fan returns to CenturyLink Field without receiving authorization a criminal complaint will be issued against the fan as a “defiant trespasser” with the Seattle Police Department.

Seahawks season ticket holders are responsible for the behavior of persons using their seats. If those persons are ejected, the Seahawks may take appropriate action against the season ticket holder, up to and including season ticket revocation.”
