CHARLOTTE – Linebacker Luke Kuechly showed up on the injury report after reporting groin soreness to the training staff Thursday morning, but there isn't concern about his availability for Sunday's game against the Los Angeles Rams.

"Didn't want to risk anything so we held him out," head coach Ron Rivera said. "He went through all the walkthroughs and all the installations. But as far as practicing, we weren't going to practice him today.

"He should be fine. Tomorrow, he should be back on the practice field."

Linebacker Shaq Thompson made an appearance at Thursday's practice but he did not participate and is not expected to play Sunday after suffering a knee injury in last week's win versus Arizona.

"It's a long, long, long shot," Rivera said. "It's tough because he wants to play and he's been a solid guy for us this year. You hate to see that happen. But, having said that, A.J. (Klein) will be in his stead. We're pretty confident with A.J."

Rivera will most likely have a tough decision to make when it comes to center Ryan Kalil, who has not yet practiced this week after injuring his shoulder against the Cardinals.

"He's a big part of who we are. He's doing everything he can," Rivera said. "He'll be mad at me if I have to make a tough decision, which I probably will. But we'll see what happens."

Rookie cornerback Daryl Worley was held out Thursday after injuring his arm during Wednesday's practice. Worley said he expects to play, but the Panthers are monitoring his soreness.

"He kind of got kneed in the back of the triceps," Rivera said. "We'll see how he is tomorrow morning. We just want to make sure he's OK."

Rookie cornerback James Bradberry (foot) practiced in full Thursday and is on track to return after a three-game absence.
