Hatcher signed with the Packers' practice squad Tuesday, Josh Tolentino of The Athletic reports.
Hatcher has spent the last two offseasons with the Raiders, and while he made the 53-man roster this year, he ended up being cut after Week 1 in order to create a roster spot for Martavis Bryant. He joins a Packers team that's been riddled with injuries at wide receiver, but Hatcher likely won't get promoted to the active roster unless the situation at the position becomes dire.
