Michael Turner, Jerious Norwood hurt
Third-string running back Jason Snelling rushed for 129 yards, caught five passes and scored three touchdowns in relief as the Falcons crushed the Cardinals 41-7.
"I'm a little tired," Snelling said after the game. "But that's the way we prepare. Coach is always telling us to focus because we never know when our chance might come."
Turner had nine carries for 75 yards before suffering a groin injury. He could have returned but there was no need to go back in with a big lead and Snelling running so well.
"That says a lot about the depth of our team," coach Mike Smith said. "He's just a darned good football player, not only running the football but catching the football."
Norwood, Turner's top backup, returned the opening kickoff 34 yards and later was carted off the field with a knee injury.
Backup running back Antone Smith is on the inactive list.
