BOISE, Idaho (AP) -- Boise State running back Jay Ajayi ran for a career-high 222 yards on 24 carries with three touchdowns to lead the Broncos to a 34-17 win over Nevada.
Backup quarterback Grant Hedrick threw for 150 yards and ran for 115 more.
Hedrick, a junior who had only attempted 36 passes in his career, took over when starting quarterback Joe Southwick injured his right foot on the Broncos' first offensive play from scrimmage. He finished 18-of-21 passing. He is also the first Bronco quarterback to rush for over 100 yards since Jared Zabranski rushed for 123 against Hawaii in 2004.
Boise State (5-2, 3-1 Mountain West) won its eighth straight game at home against Nevada.
Nevada (3-4, 2-2), which led at halftime against Boise State for the first time since 1997, lost its fifth straight on the road dating back to last season.
