The Packers placed Dafney (hip) on injured reserve Saturday.
Dafney has yet to be targeted in the passing game despite playing nearly 40 percent of the Packers' offensive snaps through the first two weeks of the season. Josiah Deguara cleared concussion protocol ahead of Sunday's matchup, but they will still only have three active tight ends against the 49ers. Dafney will miss at least three weeks after being placed on IR, so the Packers may need to make a move to add some depth to their tight end room.
