College Football: Ohio State defeats Michigan in double OT

College football fans couldn't ask for a better performance or finish in The Game, which Ohio State came out on top in double overtime. The Buckeyes victory marked the first overtime classic in the rivalry's long history. Curtis Samuel provided the walk-off touchdown after Michigan scored a field goal on its shot in the second overtime period. Ohio State originally brought the game to OT after Tyler Durbin shook off two early missed field goals with the game-tying kick in the final minute of regulation

Kentucky 41, No. 11 Louisville 38 — GameCenter

The Cardinals dropped their second straight game and Heisman favorite Lamar Jackson took another hit to his award campaign as the Wildcats took the stunning win in the in-state rivalry.

Jackson finished with more than 450 yards of offense and four touchdowns but also three costly interceptions.

Georgia Tech 28, Georgia 27 — GameCenter

The Yellow Jackets stormed back and outscored the Bulldogs 14-0 over the final frame to pick up the one-point road victory in Athens. Georgia Tech combined for 226 yards on the ground and four touchdowns while quarterback Justin Thomas only attempted 10 passes in the victory. The deciding score was set up by what appeared to be a trick play in the works, but running back Qua Searchy instead tucked the ball and carried it in from six yards out in the final minute.

LATE AFTERNOON:

No. 1 Alabama 30, No. 13 Auburn 12 — GameCenter

The Tide took the 81st edition of the storied Iron Bowl and did so in convincing fashion. Alabama outscored Auburn 17-3 in the second half and limited the Tigers to just seven first downs and under 200 yards of total offense. Jalen Hurts added three more touchdowns to his fantastic freshman campaign and the Tide now heads into next weekend's SEC championship with a perfect record and an apparent easy road back to the College Football Playoff.

No. 6 Wisconsin 31, Minnesota 17 — GameCenter

The Big Ten West champion Badgers overcame a 10-point deficit at the half by going on a 24-0 unanswered run to close the game and top the Golden Gophers.

No. 7 Penn State 45, Michigan State 12— GameCenter

While Ohio State and Michigan stole much of the headlines this year out of the Big Ten East -- as well as most of the attention this rivalry week -- it's the Nittany Lions who overcame the odds to claim the division crown. Penn State posted 35 unanswered points over the final two frames to turn a competitive game into an easy win. The Nittany Lions saw an outstanding performance from quarterback Trace McSorley, who finished 17-of-23 for 376 yards and four touchdowns.

No. 12 Southern California 45, Notre Dame 27 — GameCenter

Mike Williams was on the receiving end of three of those touchdowns, finishing with six receptions for 100 yards, and running back Wayne Gallman added 112 more on the ground in the rout. Clemson opened up a 42-0 lead before South Carolina finally reached the scoreboard in the third quarter.

No. 9 Colorado 27, No. 22 Utah 22 — GameCenter

The Buffs are heading to the Pac-12 championship game next week thanks to its sixth straight win Saturday night against the fellow-ranked Utes. Sefo Liufau finished with two touchdowns -- one passing and one rushing -- to lead the Buffs offense. Meanwhile, Colorado's defense held Utah to 6-of-21 on third down conversions and forced two fumbles in the victory. Next up for the darkhorse Playoff contenders is a trip to face No. 5 Washington for the conference crown.

No. 14 Florida State 31, No. 15 Florida 13— GameCenter

Florida may be heading to the SEC Championship game, but the Seminoles came out of Saturday's rivalry matchup with bragging rights in the three-score victory. In possibly his final game playing in front of the home crowd in Tallahassee, tailback Dalvin Cook rushed for 153 yards and a touchdown in the win. Freshman quarterback Deondre Francois added two of his own. With the loss, Florida's slim CFP hopes take a hit; meanwhile, the Seminoles may be positioned nicely for a New Year's Six bowl shot despite not playing in next week's ACC title game.
