Jordan Brookshire came off the bench to pass for one touchdown and rush for another and No. 21 San Diego State clinched a spot in the Mountain West conference championship game with a 27-16 victory over Boise State on Friday morning at Carson, Calif.

Brookshire entered late in the second quarter and led San Diego State to 24 consecutive points to overcome a 13-point deficit. He completed 11 of 15 passes for 192 yards and rushed for 46 yards on nine attempts for the Aztecs (11-1, 7-1).

The Aztecs continued the momentum on the first drive of the second half as Bell scored on a 2-yard run for a 20-16 lead. McMorris then intercepted Bachmeier for the second time and Brookshire cashed in with a 16-yard scoring run to boost the lead to 11 with 7:46 left in the third quarter.
