GREEN BAY (Packers / WFRV) -- The Green Bay Packers and the Green Bay Police Department are warning fans to be vigilant when purchasing tickets to Sunday's Packers-Vikings game.

Due to the high level of interest in the game, law enforcement officials want all fans considering purchasing tickets on the secondary market to be very diligent in knowing the source of the tickets. Counterfeit tickets were a problem for hundreds of fans at the Packers-Vikings game Oct. 5 in Minneapolis, and according to the Green Bay Police Department, it is likely the same will occur in Green Bay this weekend.

"The Green Bay Police Department is committed to working with the Green Bay Packers in a partnership to uncover any instances of counterfeit tickets for any game, concert, or other special event," said Commander Lisa Sterr of the Green Bay Police Dept. "We will be working with Ashwaubenon Public Safety, and have personnel at the Packers-Vikings game to specifically address this issue. No matter the venue, manufacturing and selling counterfeit tickets is a crime, and we will do everything possible to locate and arrest any persons dealing in such activity.

"The Green Bay Police urge fans to be careful and skeptical when purchasing a ticket from an unknown person. It is safer if tickets are obtained through a recognized ticket agent."

The Packers recommend fans utilize team partners Ticketmaster and Packer Fan Tours for purchasing tickets or ticket packages. Other ticket sources, according to the Wisconsin Bureau of Consumer Protection, should be members of the National Association of Ticket Brokers, as these businesses carefully screen ticket offers and take other measure to protect consumers from ticket fraud.

Fans are also being reminded about two time-related issues:  The game has been moved to 3:15pm, and Daylight Saving Time ends on Saturday night.. so roll your clocks back an hour Saturday night.
