The Vikings announced they have about 11,000 tickets left for Sunday?s first-round playoff game against the Philadelphia Eagles at the Metrodome. Under NFL rules those tickets need to be sold by 3:30 p.m. Thursday to avoid a blackout of the game, which is scheduled to be aired locally. However, Steve LaCroix, the Vikings vice president of sales and marketing and chief operating officer, said the team already has asked the NFL for a 24-hour extension until 3:30 p.m. Friday. The request for an extension is usually made the day of the deadline but with Thursday being New Year?s the Vikings decided to be proactive with the league.
