Vice-captain Surjan played the first 13 games last season before developing swelling in his knee and booking in for surgery during the mid-season break.
The 25-year-old was expected to miss two weeks of football, but his knee failed to fully recover and he was scheduled for more surgery late in the season.
He has been restricted to cycling and swimming and won't train with his teammates until the middle of January.
Power football operations manager Peter Rohde said the club would take a cautious approach to Surjan's rehabilitation, with the aim of getting him fit for the start of the home-and-away season.
"Surj had some pretty serious surgery to repair damage to the back of his kneecap and also some cartilage damage, so he's embarking on a long, slow and gradual build up to training," Rohde told afl.com.au.
"We play our first lot of NAB Cup games on February 11, so it's pretty early. I would think Surj would be in doubt to play in that not from the point of view that we don't think he'll be fit, but because he might not have done enough training.
"I would think he would be right for the start of the season proper, though."
Small forward Brett Ebert is also on track to play against the Pies in round one next season after rupturing his anterior cruciate ligament against Melbourne in round 22 this year.
Ebert, 27, opted to have the LARS procedure in a bid to speed up the recovery time and is already back running and doing light track work.
The one-time leading goalkicker is battling a virus, which has slowed down his rehabilitation, but fitness coach Cam Falloon said Ebert's recovery was otherwise going to plan.
"We went into the off-season wanting Brett to trim down a fraction. He had a minor setback purely because of the virus, which has probably cost him two weeks and caused him to lose more weight than we would have liked," Falloon said.
"We'll take a conservative approach with him before Christmas and look to get him back into training with the group in January. Up until then he'll be in and out of selected drills and will work on his conditioning and strength."
Half-forward Jason Davenport will also be on a modified program leading into Christmas, after having minor groin surgery last week.
Davenport walked laps of Alberton Oval with new recruit Ben Newton on Wednesday and Falloon said the former Geelong player would be back training within three weeks.
"Jase's groin injury was something we thought we were on top of at the end of the year. He had five weeks off his legs and came back feeling really good, but then he started showing some of the symptoms he had mid-season," Falloon said.
"It's not major…and given it was only going to be three weeks before we got him back onto his legs…it probably would have been the same time frame had we managed it conservatively without surgery."
