Cowboys' Rossum out 2-4 weeks

From the Associated Press:

IRVING, Texas -- Newly signed kick returner Allen Rossum is out two to four weeks because of a hamstring injury sustained on his first return with the Dallas Cowboys.

Rossum was supposed to handle kickoffs and punts but went down in the first quarter Sunday against Atlanta.

Felix Jones will be the primary kickoff returner and Patrick Crayton will handle punts. Crayton returned a punt 73 yards for a touchdown against the Falcons.

Miles Austin used to be Dallas' kickoff returner, but his rapid rise as a receiver has made him too valuable for it.
