Green Bay Packers linebacker Clay Matthews sat out of Monday’s padded practice at Nitschke Field because of knee soreness, coach Mike McCarthy said afterward.
McCarthy didn’t offer a timeline for when the five-time Pro Bowler is expected to return. Julius Peppers and Nick Perry lined up at outside linebacker with the starting offense, while Nate Palmer stepped in next to Sam Barrington inside.
“Exactly when it happened? Probably sometime Saturday. So we’re just being smart with him,” McCarthy said.
Palmer appears to be dealing with an injury, too. The third-year linebacker was sporting a club on his left hand during practice.
"He has a hand injury, so he’s clubbed up," McCarthy said. "I thought he did a good job working through it."
Receiver Adrian Coxson has been diagnosed with a concussion. The undrafted rookie was taken from Saturday’s practice in an ambulance for evaluation after experiencing “fatigue” and “light-headedness” issues.
McCarthy said second-year return Jared Abbrederis is making strides in the concussion protocol, but the Packers still signed former Fort Hayes State receiver Ed Williams on Monday because of mounting injuries at receiver.
“He’s making progress,” McCarthy said of Abbrederis. “He’s still going through the protocol. But, as I’m told, he’s definitely doing better today than he was Saturday.”
Receiver Ricky Collins (heel) remains on the physically unable to perform list with running back John Crockett (ankle) and outside linebacker Mike Neal (abdomen).
Second-round pick Quinten Rollins passed his physical and was activated from the non-football injury list for a hamstring issue he developed in the weeks leading up to camp.
On Monday's practice:
Today was installation phase No. 4. Today was red zone. Thought offense did some really good things today in practice. It takes some time. I think there's definitely peaks and valleys in our work so far. We're getting a lot of quality video to work from.
On rookie cornerback Quinten Rollins' return to practice:
Quinten was in a limited fashion today. I wanted to treat him like the rest of the team.
On the week ahead:
We have four more padded practices this week. We have a new facility and training center, so there's things we'll be able to improve on from last year. Other four practices are very important. You get all our scheme in. We walk off field on Saturday night, we'll have everything in.
On rookie quarterback Brett Hundley:
I think he's done a really good job picking it up. The quarterback room is a really good room. They've come in and picked up a complicated offense. He just needs reps. I think he's definitely improved from OTAs to this point.
On veterans easing into installation days:
I'd say offense production was good. That's what you like to see. They need to continue to do so. Defense got better today. Saturday wasn't quite what we were looking for. I thought defense did a better job getting off blocks. Started slow in first red-zone drill.
On rookie cornerback Damarious Randall's maturation outside:
Looks comfortable. Understanding his high. He's very natural. He's like any other young player. There's a certain way each player at each position is taught. He needs to continue to develop with that.
On second-year defensive tackle Khyri Thornton:
He's definitely improved from last year. He's young, raw. He's off to solid start.
On rookie linebacker Jake Ryan:
He's a bright young man. There's some things he struggled with on special teams that he's picked up, particularly footwork on punt protection. Competing against Aaron is a challenge. He's been challenging our defense.
On whether quarterback Matt Blanchard was OK after being hit:
All indications are he was.
