James Lavery gave Donegal Celtic the lead on 8 minutes when he calmly slotted the ball past Kevin Pressman.

And on 23 minutes the Hoops doubled their lead through Pay McAllister after he turned home a Lavery corner which was knocked on by Ciaran Donaghy.

The Ports pulled one back three minutes from the break when keeper Declan Brown dropped the ball at the feet of Gareth McKeown who gleefully tapped home from close range.

Then, ten minutes later, they equalise when a free-kick from the edge of the area caused confusion in the home defence with the ball finally crossing the line via a deflection off McAllister after Peter Kennedy knocked it goalwards.

Portadown's recovery is complete when they take the lead for the first time after Wesley Boyle sends a left-foot shot home after a corner wasn't cleared.
