Jordy Nelson isn't a new addition to the injury report, but Mike McCarthy did give an update on the wide receiver on Tuesday saying he underwent a procedure on his knee and will miss the rest of training camp. McCarthy is still hopeful that Nelson will return in time for the regular-season opener.

There were no specifics shared on Nelson's injury or the procedure he underwent, but ESPN's Adam Schefter did share the following on Twitter...

Jordy Nelson underwent knee surgery Monday. Expected to be sidelined 4-to-6 weeks but doctors expect him to be ready for opener.

Here's the rest of the injury updates from Tuesday's training camp practice in Green Bay...

Dropping Out of Practice

Offensive lineman Bryan Bulaga, knee

Commentary: After Bulaga played through his injury during Saturday's intra-squad scrimmage, Tuesday was the first day of practice that he missed. No decision has been made on Bulaga's future, and it would appear he and team are still trying to decide whether he may actually try to play through a torn ACL this season. They continue to wait on one more medical opinion.

Wide receiver Randall Cobb, biceps

Commentary: Cobb dropped out of practice with a biceps injury, according to McCarthy. It's doubtful Cobb's injury is serious, but the Packers are starting to become very thin at wide receiver, considering Nelson, Charles Johnson and Kevin Dorsey all remain out.

Defensive lineman Datone Jones, illness

Commentary: McCarthy said Jones missed Tuesday's practice due to illness. No specifics were provided, but it would have to be a very serious illness for Jones to miss anything more than a few days.

Running back Alex Green, knee

Commentary: Green's knee flared up on him on Monday, even after a day off from practice on Sunday, according to McCarthy. Given Green's injury history and his troubles getting back to full health from a torn ACL in 2011, there has to concern about where he's headed.

Defensive lineman Johnny Jolly, cramps

Commentary: Jolly dropped out of practice due to cramping. He fought through injury earlier in training camp and returned to practice the very next day. There's probably no reason for concern.

Tight end Ryan Taylor, knee

Commentary: Taylor originally dropped out of Saturday's scrimmage with a knee injury, but Tuesday was the first full session he's missed. McCarthy said he's probably week to week and that Taylor is pushing to get back out on the field.

Returning to Practice

Linebacker Dezman Moses, toe

Commentary: Moses was forced to miss Saturday's scrimmage with a toe injury, but returned on Tuesday. He's the only player on the roster with any experience at outside linebacker behind Clay Matthews and Nick Perry, so he's a welcome return.

Linebacker Jamari Lattimore, illness

Commentary: Lattimore has had an on-again, off-again illness that prevented him from playing in Saturday's scrimmage, but he was back in action on Tuesday. Combined with Moses, the linebacker position got a dose of good health.

Safety David Fulton, knee

Commentary: For the second time this camp, Fulton came back from knee injury. If he has any hopes of making the team, he'll have to stay healthy, because Fulton is far down the depth chart as it is.
