Eriksen has missed Tottenham Hotspur's last four games with a stomach problem.
The midfielder has missed Spurs' last four games as he's dealt with the issue and Hareide says that both club and country fear the extent of it.
"Such an injury can be chronic, and it is true that Tottenham also fears that," he told Canal 9. "It is doubtful whether we will lure him to Dublin and make him play. I do not think that Tottenham is particularly interested in that."
Hareide couldn't offer any update on Eriksen's return, either, merely saying that you'd need to speak to a doctor to determine whether he'll be out for weeks or months.
Months without Eriksen would be very bad news for Denmark but it would be even worse for Spurs; while the Danes know they'd have four games without him in that time, Mauricio Pochettino has some very important games over the next two months.
A long-term absence would leave Spurs without their chief creator for games against Manchester City, Chelsea, and Arsenal - as well as three must-win Champions League games.
For a team just about getting back on track after an early season loss of form, this could be something that seriously harms their entire season.
Spurs aren't a club that relies on squad depth but rather on their incredibly strong, well-functioning first eleven and having arguably the most talented individual missing leaves them in need of a reshuffle.
It remains to be seen if they're capable of living without him and still challenging at the top of the league, although similarly, we simply don't know exactly how long Eriksen will be out for.
There will be a lot crossed fingers in North London that Hareide is worrying over nothing.
