IRVING -- The Dallas Cowboys signed eight free agents during a whirlwind first week of free agency.
The second week has started and the Cowboys are back at work trying to add to the list, showing interest in a pair of Green Bay Packers: cornerback Jarrett Bush and linebacker Erik Walden.
First, they needed to take care of unfinished housekeeping of a week ago by officially releasing veteran guard Kyle Kosier.
It was a decision made Friday after signing the second of two guards during the first week of free agency.
Nate Livings signed a $19 million contract, including $6.2 million guaranteed, following an $11 million deal with Mackenzy Bernadeau, making the Cowboys younger up front and making Kosier expendable.
The Cowboys will save roughly $1.5 million against the cap by releasing Kosier, the final move in what has been a complete makeover of the offensive line since last summer when they released tackle Marc Colombo, guard Leonard Davis and center Andre Gurode.
Kosier, who joined the Cowboys in 2006, played in every game in 2011. However, he suffered a torn medial collateral ligament in his knee in the season finale.
The injury didn't require surgery, but it was another thing the aging guard would have to deal with after missing 13 games in 2009 and 2010 combined.
The team's interest in Bush and Walden are more about improving the depth on the roster as both would likely be backup players with the Cowboys.
Bush led the Packers in special teams tackles last season.
Walden was a sixth-round pick of the Cowboys in 2008, but didn't make the opening day roster. He was with the Kansas City Chiefs and Miami Dolphins before playing with the Packers the past two years when he had six sacks.
No visits have been set up, but the Cowboys are in the process of trying to make that happen.
