After a quiet opening, the home side are starting to apply some pressure and Chris Shields has to fling himself full length to block a shot behind at the expense of a corner.

What a chance for Crusaders!

Gruff John clears Philip Lowry's header off the line before also clearing the rebound, which no one could control.

What a crucial clearance that could be in this tie.

It's a lively artificial playing surface in Iceland.

Weather conditions are akin to a 2024 Northern Ireland summer's day.

New signing Jacob Blaney tries his luck from just outside the box, but his strike is wide.

Can Crusaders find a goal before the full-time whistle?

Darren Thomas and Jarlath O'Rourke are cautioned for an off the ball incident.

We’re underway in Reykjavik.

It’s been a chastening 24 hours so far for the Northern Irish clubs in the early rounds of European competition.

Can Linfield provide a much-needed boost this evening?

Into the final 15 minutes of the game in Bangor, with still little of note to keep you informed of as Crusaders continue to struggle to test stopper Stephen McMullan.

Richard Davies makes a change with Sam Downey replacing Matty Hill.

Ross Clarke and Ben Kennedy's evenings are over as they make way for James Teelan and Billy Vance.

Philip Lowry is the fifth player to be cautioned this evening.

Zack Clarke is booked after colliding with Daniel Larmour.

Louis Lloyd tries to flick the ball on for Zack Clarke but, under pressure from Lewis Barr, Clarke can't control the danger.

Crusaders are definitely enjoying more of the possession in the second half with both substitutes making an impact.

There are debuts for summer Linfield recruits Scot Whiteside and Cammy Ballantyne, while Sam Roscoe-Byrne makes the first appearance of his second spell for the club.

Ross Clarke's in-swinging corner is nodded on by Adam Lecky, but the effort takes a deflection which gives Caernarfon time to clear their lines.

It's been a much more even start to the second half.

Linfield boss David Healy says his side have "unfinished business" in the Europa Conference League ahead of their first qualifying round first leg against Stjarnan.

The Blues were agonisingly beaten by Latvian side RFS 4-2 on penalties in the final qualifying round before the group stage in 2022.

That was the closest any Irish Premiership side has come to reaching the group stage of a European competition and Healy admits the dramatic defeat still haunts him.

"For me, it is one I look back on and think it is a huge regret that we didn't progress how we should have done," he told BBC Sport NI.
