Mike Neal sacks Jake Locker

The Green Bay Packers opened training camp today and it wouldn’t be football season if they didn’t have 17 guys injured. Okay, it’s only seven.

The Packers put defensive end Mike Neal, running back DuJuan Harris, tackle Derek Sherrod, defensive end Jerel Worthy, guard J.C. Tretter and safeties Sean Richardson and Chaz Powell on the physically unable to perform list for the opening of camp.

Some of these moves come as a surprise.

Neal participated in all of the team’s offseason activities and minicamps. The Packers were experimenting with him at outside linebacker.

Harris, meanwhile, had a cyst removed from his lung, but said earlier this summer he expected to be ready for training camp.

Sherrod, somehow, is still recovering from a broken leg he suffered late in 2011. He missed all of last season. Richardson is recovering from a neck injury he suffered last season.

Tretter and Worthy were expected to be here. Tretter broke his ankle during OTAs and Worthy is recovering from a torn ACL, which he suffered in December.

The good news is these guys can be activated from the PUP list at any time during training camp. However, if they aren’t activated, they’ll be sitting out the first six games of the season.
