The Arizona Cardinals have already made a couple of key moves in free agency, most notably agreeing to deals with offensive tackle Jared Veldheer, offensive guard Ted Larsen, wide receiver Ted Ginn, Jr. and cornerback Antonio Cromartie.
On Tuesday, the team made two more signings, agreeing to deals with a pair of cornerbacks, according to Darren Urban of AZCardinals.com.
Aaron Wilson of The Baltimore Sun and The National Football Post first reported Lewis’ deal.
Lewis went undrafted out of Arizona State in 2011 and saw his first action with the Dallas Cowboys in 2012. After being released mid-season, he had four tackles and an interception in five games with the Tampa Bay Buccaneers.
Whitley has not played in an NFL game.
