As noted by Mike Rothstein, the corollary move was waiving undrafted free agent guard Andrew Zeller.
Copeland has not played in the NFL, though he is not a rookie. He spent each of the last two seasons on injured reserve with the Jacksonville Jaguars after being an undrafted free agent out of Louisville.
Injuries have dogged the 5’11”, 180-pound wideout for years. He missed a plethora of games during his time at Louisville, enough that he earned a sixth year of eligibility from the NCAA. When healthy, he hooked up with Teddy Bridgewater to lead the Cardinals in receptions in both 2012 and ’13.
