Ryan Mathews to make 2012 debut: Week 3's late-game inactives

The San Diego Chargers are off to a 2-0 start on the season despite playing without injured running back Ryan Mathews. But good news for San Diego: Mathews will be in the lineup Sunday against Atlanta and should get a full workload.

Here are the key actives/inactives we're tracking for the Week 3 late games.

Inactive

• Knowshon Moreno, RB, Broncos: Injury problem? Not here, that we know of. It appears that Moreno simply has been demoted deep down the Broncos' depth chart after two subpar weeks -- he has just 15 yards on eight carries thus far.

• Troy Polamalu, S, Steelers (calf): We knew earlier this week that Polamalu, James Harrison and Rashard Mendenhall likely would miss Pittsburgh's Week 3 game, and there was no change on Sunday. The Steelers believe they can make do against Oakland without risking their top players.

• Adrian Wilson, S, Cardinals (ankle): Arizona's pass defense will have to survive Sunday's test from the Eagles without Wilson, who was questionable with an ankle injury and will not be able to go.

Active

• Mike Goodson/Taiwan Jones, RB, Raiders (hamstring/ribs): The Raiders will have their full complement of running backs on Sunday. Goodson and Jones were questionable heading into the weekend, but each is healthy enough for action.

• Sebastian Janikowski, K, Raiders (groin): Janikowski seems to find his way onto the injury report more often than not. He'll be up to his normal big-kickin' ways on Sunday.
