The match between Nacka FC and Syrianska will decide which team stays in Division 2 Southern Svealand next season.
"There is reason to believe that players or team officials have been subjected to attempts to influence them before the match, so-called undue influence," the police write on their website.
Police from the Stockholm region and staff from the Swedish Football Association will be at the match to monitor events and prevent crime.
Based on the information we have, it is obvious to us that the match should be played. We do not know exactly what information the police have, but they have not recommended anything other than that the match should be played, says Johan Claesson, integrity officer at the Swedish Football Association.
Claesson says one of the teams in Sunday's match has been in contact with the association.
We have a dialogue with that club, he says.
