When the teams last met, it was an eventful one. In Uppsala, Mjällby recovered from a 3-0 deficit and went home with a point after a 4-4 draw.
On Saturday afternoon, the same scenario unfolded - improbably enough.
Sirius looked to be heading for a comfortable victory. After the first half, the away team led 3-0 after two goals by Otso Liimatta and one by Isak Bjerkebo.
Nothing is working, said home coach Karl Marius Aksum in the halftime interview with TV4.
Mjällby came out for the second half as a completely different team. In ten minutes, the team from Lister scored two goals and suddenly it was a match at Strandvallen.
Mjällby, and Jacob Bergström, were not done there. With just over a quarter of an hour left, Bergström scored twice to make it 3-3, and with five minutes left, Olle Lindberg made it 4-3 and gave Mjällby its first victory in the Allsvenskan since May.
It feels doubly good because we haven't won in a long time, said Lindberg.
For league leader Sirius, the first loss of the season is a fact.
In the second half, we don't do anything that we said we would do. I want to apologize to all the supporters who came here," said team captain Henrik Castegren.
