Paul Goodhand tucked away a penalty as Boston Town earned a point at home to Desborough.
Ar Tarn took a 53rd-minute lead through Mark Redding in the UCL Premier fixture.
However, the Poachers took just 13 minutes to draw level.
And it was dead ball specialist Goodhand who made no mistake from 12 yards out.
The result leaves Boston in 13th spot, with Desborough a place and five points in front.
