Bernie Vince and Jared Petrenko are the two highest profile Crows set to be moved from modified training programs into full contact work.
Matthew Jaensch, Ricky Henderson and Luke Thompson will also join full contact work.
Vince had a cyst removed from the back of his shoulder at the end of the season.
The 57-millimetre long cyst was pinching on a nerve and restricting Vince's weight training, forcing the decision to perform surgery.
Petrenko is recovering from a reconstruction to his right shoulder.
He told the club's website he was hopeful of returning at the latter stages of the NAB Cup, after initially fearing he would miss the Crows' opening games to the 2013 season.
In other good news for the Crows, Daniel Talia is making good progress from the broken forearm he sustained in the club's Qualifying Final loss to the Swans in September and is on-track for a round one return.
It is thought Talia's return to full contact training will have to wait until late January.
Meanwhile, the Crows have pulled off a coup against rivals Port Adelaide, snaring long-time Power recruiter Phil Bunn.
Bunn will oversee talent spotting in South Australia and Western Australia, starting work in February.
