Texas A&M and Louisiana Tech were supposed to meet to open the season, when neither team was a Top 25 candidate.
On Saturday, when the Aggies and Bulldogs play their game that was postponed because of Hurricane Isaac, both teams are ranked and ready to move up.
For No. 22 A&M (4-1), freshman quarterback Johnny Manziel has become a breakout star who leads one of the nation's top offenses. No. 23 Louisiana Tech (5-0), meanwhile, has earned a national ranking for the first time since 1999.
The game will be played in Shreveport, La.
