Larne 0-0 Glentoran
It's been a feisty few minutes at Seaview as we enter the final ten minutes of the first half.
If the tempo continues like this, I think it will be a busy night for referee Steven Gregg!

Mark Randall is in the book for a late tackle on Cammy Palmer.

Rohan Ferguson makes a good reaction save to palm away David Fisher's strike.
Fisher may regret not passing there though as Jordan Jenkins looked unmarked in the box.
Larne 0-0 Glentoran
David Jeffrey is right, both teams are certainly pushing into the final third and searching for an opening goal.
However, neither stopper has been overly tested so far.

You can see the intent, this is no game of chess - both sides are going for it!
Larne 0-0 Glentoran
Christie Pattisson shows great skill to weave his way round multiple Larne shirts with his resulting delivery into the box deflected by Cian Bolger.
The half clearance falls to Cammy Palmer, whose shot crashes into the side netting.
That was great build-up play from Glentoran's new signing.

Conor McKendry is down receiving treatment.
I'm not sure the midfielder, who was struggling earlier on with a shin injury, will be able to continue.
Larne 0-0 Glentoran
Larne can't make their first corner of the game count.
Just the one big chance in the opening 15 minutes at a packed Seaview.

Cian Bolger is a defender I admire but at times he can be a bit lax - Jordan Jenkins is on that as quick as a flash and it's a superb save from Rohan Ferguson.
Larne 0-0 Glentoran

The last men back for Larne are able to clear the danger after David Fisher had intercepted a mishit goal-kick by Rohan Ferguson.
That was a bit of a let off for the Inver Reds.
Larne 0-0 Glentoran
First shot of the game goes Glentoran's way but David Fisher's strike from range sails well over the crossbar.
Larne 0-0 Glentoran
Larne are awarded a throw-in less than 20 seconds into the game after a poor clearance from Andrew Mills goes straight out of play.
Nothing comes of it, but the Glentoran stopper will be hoping that that's his only mistake of the evening!
Larne 0-0 Glentoran
Off we go!
Can Glentoran stop Larne from making history and becoming the first team to win the County Antrim Shield five years in a row?
