"The Packers did not announce the move to reporters, but Harrell is on the PUP list on which players count against the 80-man roster," reports the Green Bay Press-Gazette.
Harrell likely will remain there until the Packers determine his future with the team. It's already been rumored that he'll miss at least the Family Night scrimmage on Sunday and the team's first preseason game.
Both defensive tackle Ryan Pickett and safety Aaron Rouse were on the non-football injury list, though there doesn't seem to be much to worry about. Rouse has taken part in every practice so far. Supposedly he has a back issue, but nobody has noted that anything has looked out of place with him at training camp.
As for Pickett, he hasn't practiced. But he didn't at the beginning of training camp last year either. Once he came back, he was his usual, solid self. Expect the same this year.
Cornerback Tramon Williams also has a sore hip flexor, but it wasn't reported that he was listed on any injury report. Williams likely will sit out today's practices and tomorrow's scheduled day off, but he's reported to be hopeful to play in Sunday's scrimmage.
