Carter, Murray can just watch for now

SAN ANTONIO -- It could be a little while before the last two picks that signed in the Cowboys' draft class actually practice.

Second-round linebacker Bruce Carter (knee) and third-round running back DeMarco Murray (hamstring) went on the non-football injury list after signing their contracts and reporting to the Alamodome.

Coach Jason Garrett hopes Murray, who strained his hamstring while preparing for training camp, will be back in "a week or so."

The timetable isn't as definite on Carter, who is seven months removed from reconstructive knee surgery after his college career ended due to a torn ACL.

Carter hopes that he'll be able to participate in at least one preseason game, but that isn't a certainty. However, he is able to run and cut without problems.

"Right now, I'm full speed," said Carter, whose goal as a rookie is to be a special teams force who earns a role in one or two defensive packages. "It's just more mental than anything else, knowing my knee can support me."
