Conference commissioners discussed the possibility of adding another game to the new college football playoff system this week.

The postseason plan approved by university presidents in June called for the national semifinals to rotate among six bowl sites, The Associated Press reported. In years the sites would not host semifinals, they would host marquee bowl games involving other highly ranked teams.

A list of details still needs to be worked out before the format is implemented in 2014, including the composition of the selection committee that will pick the playoff participants, site of the first championship game and revenue distribution.

But as of Wednesday, it seems the main plan might be tweaked to give teams that don’t make the playoff more chances to play in high revenue games, the AP said.

“They created a playoff and they had a working concept for access, but they knew that more conversations were needed,” BCS executive director Bill Hancock said Wednesday.

He said there was discussion about access and whether another game might be necessary, though he couldn’t offer any answers as to how things would turn out.

Two of the sites are already set. The Rose Bowl, between the Big Ten and Pac-12 champions, is in along with the Orange Bowl, which recently agreed to a long-term deal with the Atlantic Coast Conference.

The site of the new bowl between the Big 12 and Southeastern Conference will also be a semifinal host. Those leagues are expected to make a choice between the cities of Atlanta; Houston; Arlington, Texas; and New Orleans next month.

Two leading contenders are the Superdome in New Orleans, the site of the Sugar Bowl, and Dallas Cowboys Stadium in Arlington, where the Cotton Bowl is held.

Whichever site isn't chosen for that bowl game will have a chance of landing a spot in the semifinal rotation, along with the Fiesta Bowl in Glendale, Ariz.
