All Blacks skipper Richie McCaw and star fly-half Dan Carter are making good progress as they continue their recoveries from injury.
Carter picked up a groin injury during the World Cup, ruling him out of much of his side's trophy-winning campaign.
The 29-year-old underwent surgery a fortnight before the World Cup final and while his rehabilitation is going well, he will not make the start of the Super Rugby season.
"He is going to be back in March, hopefully for our first or second home game. He is still in rehab mode but he's looking in good shape," Crusaders coach Todd Blackadder told reporters.
McCaw had a screw inserted in his foot last year following a stress fracture and played through the pain during the World Cup before having the screw removed in November.
While happy with the rate of his recovery, the 31-year-old has not set a date for his comeback.
"I've had three weeks now out of crutches and getting back walking," he said on Thursday.
"I've done some cross training and all that, so yes, it seems to be going right.
"But actually deciding when I'll be back, you'll have to wait and see, but things are progressing as they should."
