Last week, the Chiefs needed to sell 3,500 non-club seats in order to avoid a local television blackout of their game against the Buffalo Bills.
This week, the magic number is 5,500.
The Chiefs said today they need to sell 5,500 remaining tickets for Sunday's game against the Cleveland Browns by noon Thursday, or the club's streak of 156 consecutive sellouts will end, the game will be blacked out within a 75-mile radius of Kansas City, including Topeka and sports bars with satellites.
Last week, the Chiefs received a 24-hour extension from the league until Friday to sell the remaining tickets. But with 5,500 left this week, an extension is unlikely.
