Per the Milwaukee Journal-Sentinel:
The Green Bay Packers on Thursday asked for and received an extension from the National Football League giving the franchise more time to try to sell all of the remaining tickets for Sunday's wild-card playoff game against the San Francisco 49ers at Lambeau Field.
The request for more time to sell tickets to avoid an NFL-imposed TV blackout appears to be a first for the storied franchise. For decades, the Packers have been used to full houses at Lambeau Field, even as the capacity of the storied stadium swelled. Capacity is now 80,750, third most in the NFL.
The new deadline is Friday at 4 p.m.
As of 4 p.m. Thursday, about 3,000 tickets were left, not counting the inventory available on the secondary ticket market. The face value of the tickets is between $102 and $125, depending on seat location.
League rules dictate that teams must sell out games at least 72 hours before kickoff to ensure that the game can be shown on local television (defined as markets within 75 miles). The deadline was 3:40 p.m. Thursday.
The notion that the Packers, world champions 13 times over, are unable to sell out a home game — especially a playoff game — normally would be unthinkable.
