The Cowboys are sticking their proverbial toe in the free agent market Monday by hosting linebacker Justin Durant and safeties Michael Huff and Will Allen for informational visits, according to sources. But with just $102,000 in space under the 2013 salary cap of $123,000 the Cowboys are doing no more than window shopping. According to a source, the visits should not be considered an indicator that deals are imminent with quarterback Tony Romo or linebacker Anthony Spencer to lower their cap number and free up salary room to sign free agents. Nothing has changed regarding those negotiations. But the visits are an indicator of the Cowboys interest in shoring up positions of concern at some point. The Cowboys have uncertainty at safety where projected starters Barry Church and Matt Johnson are coming off the injuries. Johnson is a huge question mark after not playing in a game or even practicing much as a rookie last year. Huff, the Irving native and the former Texas Longhorn, is the biggest name. He is a former first round pick who was released by the Oakland Raiders last week after eight years there. He has 93 career starts and has reportedly drawn interest from the Baltimore Ravens and Green Bay Packers as well as the Cowboys.
