Hargrove was suspended for allegedly having a role in the Saints' bounty program and ended up missing all of last season. He had been released in the preseason by the Packers.
Hargrove won a Super Bowl with the Saints and is a former first-round pick who has freakish athletic talent but is rounding back into shape after a long layoff. Hargrove worked out for the Cowboys several times this offseason and is back visiting the team now.
Dallas could lose DL Josh Brent to suspension with his DUI trial pending, and Hargrove is getting healthy after a minor offseason procedure.
