Bright start to the second half from the Lurgan Blues who are on the front foot from the get go.

A succession of Glenavon corners come in, but Portadown defend astutely on each occasion.

Sean Graham crosses from the left for Larne and Andy Ryan runs to the near post to meet the ball but he can't keep his header on target.

Dan Bent's back-pass is picked up by Larne keeper Rohan Ferguson as Joel Cooper attempts to slide in to intercept.

Strangely, referee Tony Clarke doesn't award an indirect free kick.

We're back under way at Mourneview Park for the second half.

Glenavon boss Michael O'Connor makes two changes at the break as Peter Campbell and John Mountney replace Stephen Mallon and Luke McGerrigan.

Neither manager makes any changes as the second half begins at Windsor Park.

I think the goalkeeper did well, Joel hesitated and sees him [Ferguson] coming and there was definitely a defender in behind so no foul.

Larne need a bit more impetus, they are too slow in possession.

Larne need to go up a gear.

Advantage Portadown at the break in this mid-Ulster derby at Mourneview Park.

Josh Ukek's strike in the nineth minute is the difference so far.

Joel Cooper's goal separates the sides at the break in the second Irish Cup semi-final.

After weathering some early Larne pressure, the big moments in the half - Ryan Schofield's saves, Will Patching's through ball and Cooper's assured finish - have belonged to the Bannsiders.

Joel Cooper tangles with Larne goalkeeper Rohan Ferguson as the pair chase a loose ball.

Cooper feels the keeper held him back and is furious with referee Tony Clarke, who sees nothing untoward in the incident.

There will be one minute of additional time at Windsor Park.

Ryan Schofield punches a Jordan McEneff corner out from under the crossbar as Larne look to exert some pressure late in the half.

Shane Andrews dishes out yet another card as Nathaniel Ferris is booked for a clash with Alex Moore.

Ferris goes for the ball just as Moore gets his hands on it, with several Portadown players feeling Ferris was very late.

Glenavon are enjoying a brief spell of pressure as they look to claw themselves back into this mid-Ulster derby.

Coleraine have been dominating possession in recent minutes but Larne almost hit back with Chris Gallagher's through ball bisecting the Bannsiders' defence.

Matty Lusty runs onto it and rounds Ryan Schofield before tapping home but the referee's assistant's flag is already up.

That one looked mighty close at first glance.

Shane Andrews reaches for his pocket for the second time as Tabu Rabby Minzamba is the next player booked.

He is cautioned for bringing down Paul McGovern in midfield.

Eamon Fyfe is the first player cautioned in this feisty mid-Ulster derby.

It was only a matter of time before someone was booked and it's Fyfe who is the first in referee Shane Andrews' notebook.

Larne have a free-kick in a promising position but Ronan Doherty takes it short and the ball runs harmlessly out for a goal kick.

It's just not happening at present for the Inver Reds.

The hosts are struggling to string their passes together and aren't creating much in attacking areas.

So far Niall Currie will be by far the most satisfied manager on the touchline.

Here is how Joel Cooper rifled in a first goal in the semi-final at Windsor Park.
