Substitute Axel Lindahl got the ball far down the edge in the penalty area and tested the chip.
It all ended with John Stenberg sending the ball straight into his own goal from close range.
Degerfors consolidates the lead in the Superettan, at the same time as the top teams Halmstad and Jönköping Södra won their matches.
It is now even about the third place, which means qualifying place.
Jönköping Södra holds the place right now but is being chased by Akropolis, two points behind.
