The Arizona Cardinals may be looking to add to their tight end depth.
According to Aaron Wilson of the National Football Post, the team recently tried out Jake Ballard.
Ballard has been working his way back tull strength following micofracture knee surgery and anterior cruciate ligament reconstruction that he underwent last year.
Ballard spent last year with the Patriots on injured reserve and was waived by the AFC East franchise in August.
Ballard, 25, spent the first two years of his career with the New York Giants, where he caught 38 passes for 604 yards and four touchdowns. A 6-foot-6, 256-pound player, he was originally undrafted out of Ohio State but quickly became a key contributor for the team.
