IRVING, Texas (AP) — The Big 12 plans to play its football championship game Dec. 19 after previously listing that Saturday and the preceding one as tentative dates.

The conference’s first public acknowledgment of a set date came Monday when it announced that a limited number of tickets will go on sale to the public Friday for the game at AT&T Stadium, the home of the NFL’s Dallas Cowboys.

While the Big 12 didn’t provide a specific number for public sales, the Cowboys have averaged 25,750 fans for its five home games so far at the 80,000-seat stadium, with a high of 31,700 against the Pittsburgh Steelers on Nov. 8.

About 10,000 tickets will be held back for allocation to the schools who play in the game.
