Penrith skipper Peter Wallace is undecided if he will extend his career into the 2019 NRL season, saying he is in no rush to decide.

Having missed the past two games after injuring his shoulder in round 10, Wallace is set to return to the Panthers side this weekend to take on the Raiders.

"It's just something that needed a couple of weeks to settle down. Basically it was just pretty sore, it's an acute injury so there's not a lot of damage in there," Wallace told AAP.

The 32-year old's body has let him down this season, also sustaining a neck injury earlier in the season. And Wallace admits that health may be the biggest barrier in him extending his deal.

"It's definitely harder and harder to get up for training as you get older, it takes you a bit longer to recover," he said.

"But mentally I'm still feeling good. I'm enjoying footy, still enjoying training.

"I'm in no rush. I'm happy to make a call on that sooner rather than later, but tossing a few things up."

Wallace is expected to either sign on with the Panthers or retire, and has already begun his coaching internship at the club's lower levels.

"Been doing a little bit of coaching with SG Ball, just a bit of kicking, with (Jersey) Flegg as well. Hopefully there'll be a role here when I finish. I've been enjoying that," he said.

Wallace will be a welcome addition to Penrith on Friday, who face a challenging draw with four players participating in Game 1 of the Origin series on Wednesday night at the MCG.
