College football roundup: Alabama edge Auburn; Ohio State end skid against Michigan

• Buckeyes dominate Michigan to stay perfect at 12-0

• Horton stars as Alabama book SEC title shot v Georgia

• Texas Tech, BYU secure championship-game berths

Isaiah Horton caught three touchdown passes from Ty Simpson to help No10 Alabama survive blowing a 17-point lead to escape with a 27-20 win over rival and host Auburn in the Iron Bowl on Saturday night.

The Crimson Tide (10-2, 7-1 Southeastern Conference) not only clinched a spot in the SEC championship game v Georgia next Saturday with the dramatic victory, but they also likely locked up a spot in the College Football Playoff.
