Trean Häcken received the fourth Linköping in an important match in the top battle in the Damallsvenskan.
Both teams chased three points to catch up with the other top teams in the table.
Häcken dominated the game in the match and took the lead in the 17th minute after a goal by Johanna Rytting Kaneryd.
And at the beginning of the second half, Elin Rubensson extended the home team's lead to 2-0 when she got to a real dream match in the cross.
And as if the uphill was not steep enough for Linköping.
In the 70th minute, Linköping's team captain Nilla Fischer gave an ugly backhand after a close match where she hit a Häcken player.
The referee had to consult with the fourth referee for a while before she showed the red card and Fischer had to leave the pitch.
Häcken took home the victory in the match with 2-0 and now goes up in the league lead in the Damallsvenskan.
One point ahead of Rosengård who has one match less played.
