The only goal of the match was scored by Therese Åsland on a penalty ten minutes into the second half.
The penalty came after Mimmi Larsson was pulled down by Louise Lillbäck.
During the first half, BP had a ball that danced on the goal line.
It's not just dancing, it's far inside. So it's really bad by the referees, I think, but it's as usual," said Frida Thörnqvist to Viaplay at halftime.
It's sad that the referee should miss in quite a few matches, match-deciding moments, it can make a big difference to get an early 1-0 lead," continued Thörnqvist.
Djurgården tops the table with 21 points, two ahead of Hammarby and three ahead of Häcken.
On Saturday, previous league leader Hammarby lost to Kristianstad with 0-2.
On the other side of the table, Linköping continues to have a tough season. The second-to-last team lost to Piteå with 1-2 and has collected five points in nine matches.
