According the Todd Archer at the Dallas Morning News, Cowboys receiver Miles Austin suffered a sprained lateral collateral ligament in Sunday night's victory over the Washington Redskins.

The injury could sideline the receiver/kick returner for up to four weeks.

He recently replaced Patrick Crayton as the 3rd receiver, but Crayton should see the field again with this news.

Austin made a critical 3rd down reception from Tony Romo on Sunday night when the quarterback sent a shovel pass in his direction and he caught it just past the first down marker.

As for kickoff duties, it won't be that large a hit if rookie Felix Jones can reutrn this Sunday against the San Francisco 49ers.
