College football Week 7 live updates: Top plays and games - ESPN

Week 7 of the college football season features some unlikely undefeated teams out to prove their place among the College Football Playoff contenders.

No. 14 Missouri hosts No. 8 Alabama, while No. 7 Indiana travels to face No. 3 Oregon. The Ducks are 7-0 at home all time in AP top 10-ranked matchups. The upstart Hoosiers, meanwhile, lost both of their top 10-ranked games last season.

Both teams, with Oregon's Dante Moore and Indiana's Fernando Mendoza, have Heisman contenders and NFL hopefuls at QB.

The week starts with No. 1 Ohio State in its second ranked matchup of the season, this time against No. 17 Illinois. The Buckeyes' defense has been going off, not allowing more than nine points in a game this season.
