Almost an instant impact from Rayhaan Tulloch, who tries his luck from distance, but a Glens defender gets in the way and deflects it behind for a corner.

Crusaders go close as Elliot Dunlop hares away down the right and into the box.

However, his attempted pass is blocked and Carrick escape, perhaps he should have shot himself there.

James Teelan makes way for Rayhaan Tulloch, on for his Portadown debut.

Surprising call if you ask me - Teelan’s been one of the hosts’ livelier outlets. Then again, there’s a reason Niall Currie’s in the dugout and I’m up here with a laptop.

Ballymena defender Ali Gould, forward for an attack, slides in on Kyle McClelland and goes into referee Declan Hassan's notebook.

Jordan Stewart, hero in defence moments ago, almost makes his mark up top.

The former Crusaders man spins away from Steven McCullough and lets fly, but it hits the side-netting.

Danny Gibson gets his second and Carrick's third to equalise in a remarkable game at Seaview.

Ahu Obhakhan hangs one up towards the back post for James Teelan, but Jordan Stewart gets back to nod it clear before the winger can pounce.

Jack Malone curls the resultant free-kick over the crossbar and Ballymena have the opportunity to clear their lines again.

Ballymena's Joel Thompson brings down Stephen Mallon just outside the penalty area and is booked.

A good position for the Lurgan Blues as well.

Liam Burt thinks he’s doubled the Glens’ lead, guiding a half-volley past a wrong-footed Aaron McCarey, but the assistant’s flag is already up.

The celebrations are cut short and the home side can breathe again.

Barney McKeown heads a Jack Malone corner towards goal but Ballymena defender Ai Gould is well positioned to clear.

Glenavon have certainly looked much more positive since the break.

Eamon Fyfe races past the Glentoran backline and fires a low ball across the box towards James Teelan.

The pass is a poor one, though, and Andrew Mills gathers it with ease. A real waste from the midfielder.

Back underway at Seaview.

We're back underway here at Shamrock Park.

The Glens get the second half started, kicking from right to left. All eyes are on whether Niall Currie's side can finally turn their dominance into a goal.

The second half begins with a double change from Glenavon as Francely Lomboto and Kris Lowe replace Paul McGovern and Harry Murphy.

You've got to wonder what's being said in those changing rooms right now.

Declan Devine must surely be demanding more from his Glentoran side despite their unlikely advantage.

As for Niall Currie, does the experienced boss tell his Ports to stick to their guns and keep doing what they've been doing, or does he tear up the script for the second half?

We are about to find out shortly.

Carrick looked down and out after 30 minutes but are right back in this one after Danny Gibson's goal
