“That’s a good example where we need the answers and we don’t have them yet nor are expecting them yet,” Anderson told ABC Grandstand on Sunday.
“But we will need those answers in regard to what our list numbers look like and how we fit the salary cap within that. We’ll need to work through all of those ramifications and contracts.
“In the crisis moment we’re living through, there’s just so much complexity.
“There are more questions than answers in some areas – player contracts and list size is a key one of those.”
All-Australian ruckman Grundy signed a long-term deal late last year reportedly paying $1 million a season.
But the Magpies’ financial squeeze will only intensify with the contracts of fellow stars Jordan De Goey and Darcy Moore as well as skipper Scott Pendlebury set to expire.
Anderson said the club hoped to honour current contracts but didn’t guarantee that would be the case.
“The reality is that we’ve got contracts in place with all of our players, and we’ve made commitments,” he said.
“The whole dynamic with all players across the league might change so it’s a hypothetical question but in putting pen to paper we committed and Brodie committed and that doesn’t change.
“The principle that a contract is a contract is absolutely fair. We all want to respect that.
“The great unknown of this whole scenario though is that we’re now in a totally different world.”
Meanwhile, young Magpies forward Jaidyn Stephenson said the enforced break would give him time to make up lost ground after his pre-season illness.
Stephenson missed Collingwood’s round one win over Western Bulldogs but told Nine he wasn’t surprised by his omission.
“It wasn’t really a shock to me – I was expecting it,” Stephenson said on Sunday.
“Obviously, I didn’t have the greatest of pre-seasons with the glandular fever pre-Christmas, and then I came back and probably did only four weeks of full training with the group.
“I also had to withdraw from the Wangaratta match against Richmond due to personal reasons.
“But I think I was doing everything right and I was on my way and hopefully would have been in the side very shortly.”
Stephenson said he was fully recovered and had moved home to spend time with his family, while train in a make-shift gym at their property.
