The home side advanced to the BetMcLean Cup semi-finals after an enthralling cup tie at Seaview.

The Crues looked to be cruising after first-half goals from Harry Jewitt-White and Kieran Offord, but John McGovern and Leo Alves' late penalty rebound forced extra time.

The additional period belonged to Kieran Offord, whose clinical hat-trick proved decisive as the north Belfast side eventually ran out comfortable winners. A memorable night of cup football ends with Declan Caddell's men marching on to the last four.

Kieran Offord claims possession of the match ball with his third to put the game beyond the Swifts.

Here's how Kieran Offord scored his second of the evening early in extra-time.

One minute of additional time to be played at the end of extra time. Declan Caddell's men are on the verge of securing their place in the BetMcLean Cup semi-finals.

It's a double change for Crusaders in the dying moments.

Hat-trick hero Kieran Offord receives a well-deserved ovation as he makes way for veteran Jordan Owens, while 16-year-old Jordan Williamson replaces Robbie Weir.

John McGovern looks to release Andy Mitchell but puts too much weight on the pass. A frustrated Mitchell can only watch as the ball rolls harmlessly through to Jonny Tuffey for a goal kick.

Cahal McGinty tries his luck from long range, but his effort flies off-target of Jonny Tuffey's goal.

Signs of desperation creeping into the visitors play.

John McGovern rises to meet Kealan Dillon's free-kick but can't direct his header on target, leaving the striker with his head in his hands.

Time running out for the visitors.

Dungannon Swifts are showing some early intent after the restart, but they're yet to create anything meaningful.

The Crusaders' defence, marshalled by Jonny Tuffey, has dealt comfortably with any threat so far in this final period of extra time.

We're back underway for the final fifteen minutes of extra time.

A commanding extra-time performance so far from the Crues, with Kieran Offord the difference maker.

His two clinical strikes in the first period of extra time have put clear daylight between the sides. Fifteen minutes remain for the Swifts to produce something extraordinary, or it's the hosts who will be marching into the BetMcLean Cup semi-finals.

More brilliant attacking play from Declan Caddell's men!

Ross Clarke delivers a teasing low cross to find Kieran Offord in the six-yard box. The striker's first-time effort is brilliantly saved by Solis Grogan before Jordan Stewart's acrobatic follow-up volley sails over the crossbar.

The hosts are looking to kill the game off completely.

Kieran Offord is on the hunt for a fourth!

The hat-trick hero breaks through once again, but this time Patrick Solis Grogan gets down well to deny the striker. The forward is having a field day against this tiring Swifts defence.

Kealan Dillon tries his luck from long range, but his speculative effort sails well wide of Jonny Tuffey's goal. A wasteful attempt from the former Warrenpoint Town midfielder as precious minutes tick away.

John McGovern finds space on the right to deliver a dangerous low cross, but Jimmy Callacher shows good defensive awareness to clear the danger.

Lewis Barr's night comes to an end following that injury as Mal Smith enters the fray.

Here's James Douglas that gave Glentoran their third win over Linfield this season and secured a last-eight spot for Declan Devine's side.

There is a momentary pause in the action as Lewis Barr receives medical attention.

The physio is on to treat the defender, and both teams take the opportunity to catch their breath in what has been an intense opening period of extra time.
