The first yellow card goes to Glenavon's Sean Carlin for pulling back Kian Corbally by the arm in the middle of the pitch.

Josh Ukek takes it down nicely just outside the box and has a go with his left, but it’s straight at the keeper. More a gentle back-pass than a serious test, but the Ports' attacker has looked lively so far.

An injury to Glenavon's Paul McGovern gives players from both sides a welcome opportunity to take some fluids on board.

It's been a high-energy, but so far, low-quality opening in the Lurgan sunshine.

Portadown and Glentoran are still battling it out in search of the opening goal at Shamrock Park.

First change of the afternoon for the Glens. It's an earlier than expected debut for Liam Burt, who comes on to replace David Fisher.

Looks like the striker has picked up a knock, which will be a worry for Declan Devine.

The first effort on target comes from Glenavon full-back Ben Wilson but his daisy-cutter trundles harmlessly through to Sean O'Neill.

This is end to end stuff at Seaview.

This time it is Crusaders who go close. Elliot Dunlop crosses to the centre of the box where Fraser Bryden shoots from close range, but Nathan Gartside in goal does superbly to get down low and keep it out.

It has been your typical start to the season; it is high energy but not a lot of quality. The game is yet to settle down.

James Teelan skips away from Ciaran Coll down the right, but the Glens defender isn’t done yet and gets back to make the block.

Teelan’s straight on the loose ball, but Danny Amos gets in the way and it bounces off the Portadown winger for a goal-kick.

On first viewing I thought it was a penalty, and the referee had the whistle to his mouth but didn't blow.

Ballymena almost get themselves into a tangle deep inside their own penalty area with defenders Ali Gould and Stephen O'Donnell each leaving a clearance to each other. Both are relieved to see their goalkeeper Sean O'Neill clear the danger.

Carrick think they should have had a penalty.

Joe Crowe races across the area to get on the end of a Paul Heatley cross but appears to be brought down.

Referee Mark Dillon put his whistle to his lips but then waves play on to the disgust of away players and fans.

A massive chance for the Ports on the counter, a three-on-two situation.

Eamon Fyfe decides to go for it himself, blazing a shot from the edge of the box, high over the bar. You can see Josh Ukek and Ahu Obhkhan were queuing up inside the area, and the pair are not at all happy with the former Coleraine man.

Fraser Bryden nets two minutes into his Crues debut to open the scoring at Seaview.

It's been a slow opening at Mourneview Park with the early stages punctuated by regular use of referee Declan Hassan's whistle and the assistant referees' flags.

Carrick have recovered well from the goal and are controlling possession and territory.

Crusaders' new 'keeper Musa Dibaga almost get into trouble as he attempts to round a Rangers' striker close to his own goal line, but manages to clear.

Then Adam Lecky curls a shot from wide right against his old side but it drifts just wide of the far post.

Can't take your eyes off this one so far.

A huge let-off for The Glens moments ago, but now they've created a big chance of their own.

Jordan Jenkins whips in a lovely cross from the left, picking out James Singleton at the back post. He gets a free header, but Aaron McCarey comes out to swarm him, doing just enough to put off the midfielder as the effort glances wide of the far post.

James Teelan threads a pass to Eamon Fyfe, who takes a touch and lashes a low effort across the face of goal.

You can almost feel the collective intake of breath as it slides inches wide of the far post.

A hopeful ball is punted over the top, intended for Josh Ukek to chase down the right flank. But the Glens' goalkeeper, Andrew Mills, is quickly off his line to collect it cleanly, snuffing out the danger before it can materialise.
