Allsvenskan leaders Elfsborg suffered just their fourth league defeat of the season on Sunday after going down 2-1 at Kalmar. Anders Svensson put the visitors ahead after 39 minutes and they seemed well placed to extend their lead at the summit, which stood at six points at the start of play. But Daniel Mendes equalised shortly before half-time and substitute Melker Hallberg struck the winner a minute from time. Orebro remain rooted to the foot of the table following a 2-1 defeat at home to Hacken. Goals inside three minutes from Dioh Williams and Rene Makondele put Hacken in control with Marcus Astvald netting the hosts\' sole consolation.
