Johnson scores 3 TDs, Air Force beats San Jose State, 37-16

COLORADO SPRINGS, Colo. -- A late San Jose State turnover paved the way for D.J. Johnson 's fourth-quarter surge. Johnson ran for 103 yards and three touchdowns, all in the final quarter, as Air Force pulled away to beat San Jose State 37-16 on Saturday night. Quarterback Nate Romine added 116 yards rushing, running for a score and setting up another before leaving late in the game with a leg injury. Tyler Ervin ran for 121 yards and a touchdown and also caught a 17-yard scoring pass from Kenny Potter for San Jose State (1-1, 0-1 Mountain West). The Spartans were trailing 17-16 when Potter threw behind Tim Crawley and the ball skipped off his hands into the arms of Kalon Baker , who made his first career interception. "That was a huge play, a gigantic play," Air Force coach Troy Calhoun said.
