Half chance for the Dons as Christian Ramirez helps a ball onto Ryan Hedges.

The Welshman is caught in two minds whether to lift it towards goal first time or take a touch at the tight angle but ends up knocking it behind.

The Turkish side are pressing for an opening but the home fans are roaring the men in blue on, cheering every tackle.

Should Hibs turn things around against Rijeka, they will face PAOK in the play-off round after their aggregate win over Bohemians.

The Greek side suffered a shock 2-1 loss to the Irish outfit in the first leg but a 2-0 win on home soil gets them through.

They'll watch proceedings in Croatia with interest.

Kyogo Furuhashi is at the centre of everything, but this time it's magic from Tom Rogic.

The Australian picks out Ryan Christie wide on the left with a brilliant pass. Christie knocks it into the area first time, but Furuhashi can't get a connection on it.

Pittodrie is an absolute cauldron of noise just now, a home goal would blow the roof off.

That's Hibs under way again in Croatia and they have to improve in the second half or face a European exit.

Rijeka put plenty of pressure on in the first half and Hibs must find a response without leaving themselves exposed at the back.

Gunnlaugsson has looked dangerous on the right for the Icelanders as he again skips to the byline and drills in a dangerous low ball.

No one in the middle to get on the end of it, though.

Kyogo Furuhashi races onto a James Forrest through ball and picks his spot in the far corner, but the assistant referee's flag denies him his fifth goal in three games.

Here we go for the second half at McDiarmid Park.

They won't be far behind in Croatia... Can Hibs mount a comeback there?

Stephen Glass' men look happy to give up the ball early on.

The visitors do look tidy on the ball but no clear-cut chances as of yet. Ryan Hedges' pace on the break could be crucial tonight.

It's all Celtic in the opening minutes. Defender Stephen Welsh gets up highest to a David Turnbull cross but can't get enough on it to trouble the goalkeeper.

Aberdeen skipper Scott Brown is well up for this, he relishes these occasions.

The midfield general has crunched into a couple of challenges early on.

The visitors have enjoyed some early possession but Aberdeen show their threat on the break as Ryan Hedges strides onto a ball over the top.

Christian Ramirez is free in the middle but Hedges' pass is blocked behind. He should probably do better.

A tame penalty appeal comes from the resulting corner but the Icelanders survive.

It's definitely a three at the back tonight for Stephen Glass' men.

Ross McCrorie, Declan Gallagher and Andy Considine are the three centre-halves with young wing-backs Calvin Ramsay and Jack MacKenzie operating the wide areas.

Jack Ross has a big half-time talk ahead of him.

Rijeka eventually broke the deadlock on the stroke of the interval but the hosts could have scored another couple as they continue to target right-back Paul McGinn.

Hibs have had chances but they have been few and far between.

What a chance for Celtic inside 40 seconds.

Kyogo Furuhashi is clean through on goal, tries to dummy the goalkeeper, but Jan Hamus manages to get a foot to it and deny the striker.

Absorbing stuff in Perth as St Johnstone go toe-to-toe with the Turkish giants.

Callum Davidson's side have reacted well to falling behind, with Chris Kane grabbing the equaliser from a corner, thanks to some suspect goalkeeping.

We are up and running at Celtic Park and Pittodrie...

Another shot for Zander Clark to deal with and again it's right at him as Kerem Akturkoglu takes aim from 20 yards.
