Potential free-agent targets for Cowboys

The Dallas Cowboys have $9.7 million in salary-cap space to sign their remaining draft picks without contracts and potential free agents.

Here are five free agents with the potential to join the Cowboys in case of injury:

Laurent Robinson. He's on the market because of health issues. He didn't recover from a concussion last season while in Jacksonville, but Cowboys officials are more concerned about an ankle injury. When Robinson played with the Cowboys in 2011, he caught 54 passes for 858 yards and 11 touchdowns. The Cowboys couldn't afford him when he hit the free-agent market, but if something happens to one of their receivers, they can pick him up for the veteran minimum now.

Winston Justice. The Cowboys expressed interest in the right tackle but were able to get Doug Free to accept a pay cut to stay with the team. If the Cowboys want a veteran tackle, Justice is available. His salary demands were a little high a few weeks ago, but he could lower them as the season nears.

Cedric Benson. The Cowboys drafted Joseph Randle in the fifth round to complement DeMarco Murray, who has battled injuries the past two seasons, and serve as an insurance policy if Murray is injured again. Benson has endured some off-field issues, but he could be a nice pickup in case of injury.

Sedrick Ellis. Health and age are concerns with the projected starters on the Cowboys' defensive line. Ellis would be a nice signing in case one of the tackles, Jay Ratliff or Jason Hatcher, goes down. Ellis has drawn interest from several teams, so his availability is a question mark. Anthony Hargrove is also on the roster, is somebody who can play defensive end and tackle, and provides the team with veteran depth.

Ronde Barber. He's retired and headed to television, but with inexperience at the Cowboys' safety position, maybe he'll return. Barber knows the Tampa 2 defense and is a veteran whom defensive coordinator Monte Kiffin trusts. It would be for only one season, and pairing him with Barry Church could be seen as a positive.
