Todd Archer reports that the Cowboys are working out offensive linemen Kelvin Palmer and Audrey Walker on Saturday.
Palmer, 25, wound up signing on with the Cardinals as an undrafted free agent out of Baylor back in 2014. He lasted one year in Arizona before he was waived shortly after last year’s draft.
After a brief stint with the Chiefs, Palmer signed on with the Steelers in July before he was waived and placed on season-ending injured reserve at the start of the 2015 season. Pittsburgh would later waive him with a failed physical this past February.
Palmer has yet to appear in an NFL game.
