Update: NFL Network's Ian Rapaport reports that Clayborn is staying with the Atlanta Falcons.

The #Falcons are keeping Adrian Clayborn to a 2-year deal, source said. He gets $9M base with a chance to make $14M — Ian Rapoport (@RapSheet) March 10, 2016

Original story: Adrian Clayborn is one of the players on the Cowboys radar heading into free agency, a source said.

The club's interest in the defensive end is no surprise. The Cowboys kicked the tires on him at this time last year before he signed with Atlanta. While not a high-profile target, Clayborn is the sort of player the club has acquired to plug into the defensive line in recent years. Think of Jeremy Mincey and George Selvie.

Clayborn started four of 16 games for the Falcons last season and finished with three sacks. He has 16 sacks and five forced fumbles in his five seasons in the league. He's 27.

Clayborn missed 13 games in 2012 with a torn knee ligament and another 15 games two years later with a torn bicep.

Recently, Jon Machota was asked in a chat about top priority for the Cowboys in free agency.

Wrote Machota: "Getting their own players signed. I think bringing back Rolando McClain, Morris Claiborne and Jack Crawford are near the top of the list in that regard. As far as free agents from other teams, it has to be pass rush. Perhaps Mario Williams or Adrian Clayborn. I believe Olivier Vernon is out of their price range."
