LARAMIE, Wyo. (AP) - D.J. Harper rushed for 105 yards and two touchdowns to lead No. 21 Boise State past Wyoming 45-14 Saturday for its seventh straight win.

Harper scored on runs of 12 and 3 yards, and Joe Southwick completed 20 of 28 passes for 198 yards and one interception for the Broncos (7-1, 4-0 Mountain West). The Boise State offense was an efficient 12 of 14 on third down conversions and scored on all five its red zone opportunities.

Boise State's defense held the Cowboys below their 25.6 scoring average, recorded four sacks and limited Wyoming to 106 yards below its average.

Wyoming (1-7, 0-4) was without head coach Dave Christensen, who was fined $50,000 and suspended by the school for the week over his conduct after a 28-27 loss to Air Force on Oct. 13.
