GREEN BAY — Ryan Pickett's arm injury could have been worse, but the Green Bay Packers' run-stuffing defensive tackle's status for Sunday's game against the Indianapolis Colts at Lambeau Field is in some doubt, coach Mike McCarthy said Monday.

Pickett suffered a strained triceps during the Packers' 27-17 victory over the Seattle Seahawks, and McCarthy said Pickett's practice time could be limited again this week.

Last week, Pickett had a flareup of knee tendinitis and saw limited snaps in practice as a result. Pickett had an MRI Monday and was examined by team doctor Pat McKenzie.

"I don't know how much practice time Dr. McKenzie sees him being able to work through. Just like a lot of these injuries, we'll see where Ryan is on Wednesday," McCarthy said Monday afternoon. "But I'd probably label him as questionable if I had to today."

Although Pickett said he was in pain after the game, he also said he would not miss this week's game because of the injury.

"I'm not worried," Pickett said.

Said McCarthy: "When you look at the big guys, and you look at (left tackle) Chad Clifton and Ryan Pickett and what some of our guys have played with in the past, you always probably have a little more hope just on a normal basis. (The triceps) is something that we're just going to have to get more information on throughout the week. Ryan's a pro.

"He's played with a lot of different types of injuries throughout his career, so I wouldn't be surprised if he's able to fight through this."

As for other injuries, McCarthy said McKenzie didn't think safety Aaron Rouse's mild concussion was serious enough that Rouse wouldn't be allowed to practice on Wednesday. And backup halfback Brandon Jackson should be back in action after flu-like symptoms Saturday night prevented him from playing Sunday.

McCarthy said quarterback Aaron Rodgers' right (throwing) shoulder was no worse for wear after the game, despite absorbing several big hits.

"(Rodgers) didn't have a setback, that's how it was described (by McKenzie)," McCarthy said. "We're hopefully moving forward. He's sore again today, which I think is normal. He'll be dealing with that for some time. But we didn't have any setbacks."

Harrell set to go

With Pickett ailing, the timing couldn't be better for the return of 2007 first-round pick Justin Harrell, who is eligible to come off the physically unable to perform list this week. Harrell will practice Wednesday, and the Packers have a three-week window to decide if they want to activate him. Harrell missed all of training camp with a back injury that required a pair of surgeries.

"He'll be full (participation in) practice Wednesday and we'll just see how he does throughout the week," McCarthy said. "He hasn't been in that particular environment for quite some time, so (the doctors and trainers) just want to make sure they give him the proper progression of working his way through a full week of practice."

Asked if it's possible that Harrell will play against the Colts, McCarthy said, "I want to see him practice Wednesday and Thursday through the padded work (before making a decision). I'm sure Friday's evaluation from Dr. McKenzie will play into that. But the first step for Justin is to go through a week of practice."

Hamstrung

McCarthy said the decision to move rookie No. 3 halfback Kregg Lumpkin to season-ending injured reserve was the result of Lumpkin re-injuring his troublesome hamstring during practice on Thursday.McCarthy had said after that practice that Lumpkin had "a chance" to be activated for Sunday's game.

Instead, DeShawn Wynn was called up from the practice squad and had a key blitz pick-up on Rodgers' 45-yard touchdown pass to Greg Jennings.

As about the multitude of hamstring injuries the team has had this season, McCarthy said, "I think every year you have the 'injury of the year,' and we have had a number of hamstrings. We've had a number of knee sprains, too. It just kind of goes that way. If I thought there was something that we were doing as far as our practice structure or what we were doing in our strength and conditioning program, we would have changed."
