Dylan Cantrell knows Kliff Kingsbury's offense, having played for the coach at Texas Tech.

What he doesn't know quite yet is the position of tight end, which is where his former coach plans to use him in their reunion with the Cardinals.

The Cards signed Cantrell Monday with the intent to move the 6-foot-3, 240-pounder from wide receiver. To make room on the roster, the Cardinals released cornerback Sojourn Shelton.

Cantrell was drafted by the Chargers in the sixth round in 2018, spending most of the season on the practice squad before being promoted to the active roster in December (the Chargers cut tackle Joe Barksdale for the roster space; Barksdale later signed with the Cardinals.) Cantrell was released in the offseason of 2019 after dealing with shoulder issues.

Cantrell did see some time as an H-back under Kingsbury at Texas Tech, where he caught 158 passes for 1,873 yards and 18 touchdowns over 46 games. The high school teammate of Patrick Mahomes was seen as one of the better blocking wide receivers in his draft class.

At tight end, the Cardinals already have Maxx Williams, Dan Arnold, Darrell Daniels and undrafted rookies Tyler Houston and Ryan Becker.
