Jim Gardiner's Loughgall side will face Linfield in the next round

Two first half goals from David Irwin seemed set to earn Banbridge a last 16 meeting with Linfield.

However, Ally Wilson pulled a goal back on 72 and Stevie Coulter half-volleyed the equaliser two minutes later.

Topley's winner came after Coulter's shot had been well-saved by Banbridge goalkeeper Stephen Haveron.

Former Portadown player Irwin put Town in front with a great first-time finish on 28 minutes over the head of Loughgall goalkeeper Marc Robinson.

Irwin then notched his 19th goal of the season when he chipped the ball over Robinson after a mix-up in the home defence.

Banbridge looked in control at half-time but Loughgall had other ideas.
