Krakouer has been strongly linked to the Gold Coast Suns, but media reports on Wednesday suggested the West Australian was also weighing up a move back across the Nullarbor.
Primus, who met with Krakouer last week, denied the 22-year-old had already told the club of his intentions to leave but said it was unlikely he would be wearing Power colours next season.
“We’re not quite sure what Krak’s doing. I spoke to him last Friday and he was saying that he was more than likely going to go somewhere else, but that he wasn’t quite sure on what he was doing,” Primus told SEN on Wednesday.
“We reiterated with him that we’d like him stay here… but he certainly hadn’t committed to us or to anyone else - that’s what he told us anyway… the longer it goes on the less likely it is that he’s staying.
“It’s not looking too good, but I daresay that with what Nathan Bock did yesterday things will probably speed up with people, who are tossing up what to do there.”
On Tuesday, Adelaide defender Nathan Bock declared he would join the Gold Coast Suns next season.
Bock’s actions have put pressure on other players, who are planning to play with Gold Coast in 2011 - and who are not taking part in finals - to reveal their decisions.
Adelaide elected to cut all ties with the former best and fairest winner and Primus said he would do the same if Krakouer were to come to him to say he was leaving.
“Krak’s not playing with us because he’s got a groin problem, but I don’t think he could [play] if he decided that he was heading off to the Gold Coast now,” Primus said.
“We’re in a situation where we’re playing some of our kids anyway, so he wouldn’t get a game in front of them because of that.”
A homesick Krakouer came close to walking out on Port Adelaide at the end of 2008, but was talked into staying by former coach Mark Williams.
Krakouer's partner Teresa and 18-month-old son Nathan Jr are currently splitting their time between Adelaide and Alice Springs.
On Tuesday, Adelaide coach Neil Craig expressed his distaste over the nature of Bock’s departure and the imminent introduction of free agency in the AFL.
Primus echoed his cross-town counterpart’s sentiments, but said in-season defections were something the clubs and their supporters would have to learn to deal with.
“It’s not ideal and you can lose some very good players,” Primus said.
“Krak is nowhere near the age that Bocky (27) is, but we think he’s a pretty talented kid and we’ve put a fair bit of effort into him over the last three of four years.
“It’s disappointing in that regard, but we all knew this was coming and we’ve just got to work with it.”
The Power are at risk of losing another key player at the end of the season, with injured midfielder Steven Salopek contemplating a move back to Victoria.
