The Packers worked out three receivers on Wednesday. They signed one, filling the roster spot opened earlier in the day with the release of outside linebacker Caliph Brice.
Ishmael Hyman has signed with the Packers, his agency announced on social media. Matt Cole and Derrick Dillon were the other receivers to receive a workout.
Hyman played with the Michigan Panthers this spring, becoming the 21st USFL player to sign with an NFL team. He made 15 catches for 158 yards and two touchdowns in four games.
The Packers previously signed tight end Sal Cannella and receiver Osirus Mitchell, both of whom also played in the USFL.
