The Arizona Cardinals officially placed OT Edawn Coughman on waivers Tuesday.
Coughman, 27, originally signed with the Seahawks as an undrafted free agent out of Shaw University. He also played for the Cowboys briefly before signing a reserve/future contract with the Bills at the end of the 2014 season.
Since then, Coughman played for the Buccaneers and Texans before signing a reserve/future contract with the Cardinals back in January.
Despite playing for a number of teams since entering the NFL, Coughman has yet to appear in a NFL game.
