Final: The No. 5 Michigan State Spartans are headed to the College Football Playoff after narrowly defeating the previously undefeated and fourth-ranked Iowa Hawkeyes 16-13 in the Big Ten football championship game.

Third quarter: Michael Geiger’s 47-yard field goal with less than a minute to play in the third quarter gave the Spartans their first lead since the first quarter at 9-6.

Michigan State tied it up at 6-6 on Geiger’s 29-yard field goal with 4:23 to play in the third quarter.

An early Hawkeyes fumble led to Michigan State’s field goal.

Iowa then added a second Marshall Koehn field goal early in the second quarter.

Later in the second quarter, the Hawkeyes put together a long drive, only to have it end with a wild Spartans interception in the end zone.

The teams then traded punts before Michigan State had a final scoring chance, but Michael Geiger missed a 53-yard field goal as the clock expired on the half.

Pregame: The 2015 Big Ten football championship game between the No. 5 Michigan State Spartans and the No. 4 Iowa Hawkeyes is essentially a play-in game for a spot in the College Football Playoff.

Series history: Iowa leads 23-20-2 all-time, but Michigan State won the last meeting, 26-14 in 2013.
