Västerås secured a place in the Allsvenskan at the beginning of November after a 1–0 away win against Falkenberg.
During the celebration, two of Västerås' players, Tim Hartzell and Sidy Sow, were noticed when they each held a lit flare among celebrating supporters.
The match delegate reported the players and the Swedish Football Association's disciplinary committee has decided to fine both players.
"By holding a burning flare, Sidy Sow and Tim Hartzell have behaved in such a way that the reputation of the sport has been damaged or could clearly have been damaged," the disciplinary committee wrote in its decision.
