The Crimson Tide (2-0) hardly slowed down without Ingram, and a young defense forced Rob Bolden and the Nittany Lions (1-1) into several turnovers to end promising drives.
It was the first time Penn State was held without a touchdown since a 13-3 loss at Wisconsin in 2006. The shutout lasted until the final 10 minutes.
With Ingram sidelined for the second straight game with a knee injury, Richardson pulled a pretty good imitation. He plowed through and sidestepped tackles and scored on a short touchdown run. He also had four catches for 46 yards.
Alabama QB Greg McElroy completed 16 of 24 passes for 229 yards and two touchdowns.
