Two fourth-quarter touchdowns Friday kept No. 5 Boise State undefeated with a 45-35 win over WAC rival Louisiana Tech.

Kellen Moore threw a 12-yard TD pass to Austin Pettis midway through the quarter and Jeremy Avery bolted for a 43-yard score for the Broncos (9-0, 4-0 WAC).

Tech scored a pair of TDs in the final quarter but could not overcome their less-productive first half, in which they scored only seven points.

The Broncos racked up 507 yards of offense to Tech's 250.

Moore completed 28-of-41 passes for 354 yards, three touchdowns and one interception, which was returned 76 yards for a touchdown by Josh Victorian.

Pettis caught nine passes for 105 yards and Titus Young had nine catches for 110 yards and a touchdown.

Ross Jenkins threw for 114 yards and a touchdown for Louisiana Tech. Daniel Porter and Dennis Morris ran for touchdowns.
