Week 18’s Sunday night showdown between the Minnesota Vikings and Detroit Lions could be one of the most exciting regular-season games in NFL history, featuring two teams with 14-2 records.

With the No. 1 seed in the NFC playoffs and a first-round bye on the line, the Vikings are making significant efforts to ensure strong fan representation at Detroit’s Ford Field. The team has spent nearly $2 million to purchase approximately 1,900 tickets on the secondary market, priced around $1,000 each, according to Sports Illustrated’s Albert Breer. These tickets were then offered to season ticket holders at a much lower price, some as low as $200 per ticket.

The Lions noticed this activity and discovered the email from the Vikings offering their season ticket holders the opportunity to purchase lower-level seats for Sunday night’s game. These tickets, mostly located behind the visiting team’s bench area, were offered on a first-come, first-serve basis. The Vikings emphasized that the tickets were “intended to be used by Vikings fans and not positioned for resale.”

However, not all ticket buyers adhered to this guideline. Breer detailed instances where tickets were resold multiple times on the secondary market, attracting the Lions’ attention. The Lions contacted the NFL to flag the Vikings’ actions, but the league determined that no rules were broken.

The Vikings stated that their intention was to provide players’ and staffers’ families with better vantage points and potentially influence crowd noise near their sideline. “Given the uniqueness of this game, we wanted to offer our stakeholders—staff, family, season ticket members, and team partners—an opportunity to attend,” Vikings spokesman Jeff Anderson said in a statement to SI.

While it’s uncertain if 2,000 fans will make a significant difference in a stadium with a 65,000 capacity, the Vikings’ willingness to invest heavily to ensure a strong fan presence in this crucial road game is notable. The Lions, aiming for their first-ever No. 1 playoff seed and a hopeful first step toward a Super Bowl appearance, will have the support of their roaring fans.

The Lions previously defeated the Vikings at U.S. Bank Stadium in Week 7, with a 44-yard Jake Bates field goal securing a 31-29 victory with just 19 seconds remaining.
