BOISE, Idaho — Ashton Jeanty ran for 209 yards and a touchdown and No. 10 Boise State earned a College Football Playoff spot, beating No. 19 UNLV 21-7 on Friday night for its second straight Mountain West title.

Boise State (12-1, No. 10 CFP) is all but assured of a first-round bye in the playoffs if it maintains its ranking ahead of the Big 12 winner and finishes as one of the four highest-ranked conference champs.

Jeanty, who had the spotlight to himself to state his Heisman case, didn’t disappoint, ripping off an electrifying 75-yard touchdown run. It was his fifth TD run of 70 yards or more this season, tying LaDainian Tomlinson’s FBS season record.

Jeanty also surpassed 1981 Heisman winner Marcus Allen of Southern California to move into fourth place on the FBS season rushing list and needs 132 more to pass record-holder Barry Sanders of Oklahoma State.

Jeanty’s sixth 200-yard rushing game this season also equals the most achieved by an FBS player in a season since 1996, according to ESPN Research. He is two behind Allen’s record of 8 set in 1981.

Maddux Madsen threw a touchdown pass and rushed for another score for the Broncos.

UNLV (10-3, No. 20 CFP), which entered the game seventh nationally in scoring offense averaging 38.7 points, hadn’t been held below 23 this season.
