Niall Quinn attempts an audacious scissor kick from the edge of the box, showcasing more ambition than accuracy.

His acrobatic effort sails embarrassingly wide, resulting in a throw-in for the north Belfast side.

Second booking of the afternoon and this time it's a Dungannon player as Niall Owens is cautioned for a late challenge on Kirk Millar.

Less than 15 minutes of normal time to play at Windsor Park.

Will Linfield find a fourth and put the game to bed or can the visitors pull another one back and perhaps even rescue a point?

It does feel like a second goal is coming. Glentoran are definitely in the ascendancy and Portadown's attacks are becoming less frequent.

Shea Gordon nearly notches his second and Cliftonville's third!

Joe Gormley's deft pass presents Gordon with a gilt-edged chance. Eight yards out, the midfielder swings his left foot, but his effort whistles off-target.

Shea Gordon meets Ronan Doherty's cross to divert home his first Cliftonville goal as the Reds double their advantage.

Jordan Jenkins is the difference between the teams. The work that he and Jay Donnelly have done up front, I have been impressed with him.

It shows the benefit of being able to go out on loan, in his case he was with Dundela and scored a bucket load of goals and he has come back here looking very fit and very sharp and obviously he has got his rewards today.

The Ports just can't get any meaningful possession this half.

Glentoran bossing proceedings, but at 0-1 the game could still go either way.

McGuckin is almost immediately booked as he catches Tiernan Kelly with a high boot.

Meanwhile, Benji Magee enters the fray in place of Ryan Waide.

Michael O'Connor's afternoon ends as Keith Ward takes his place.

James Doona, sensing an opportunity, decides to try his luck from distance.

The midfielder unleashes a speculative effort, but his ambition exceeds his execution as the ball sails off-target.

Almost a fourth for Linfield and what would have been a second for Joel Cooper as his left footed strike drags just wide of the far post.

A lovely flick on from Matthew Fitzpatrick tees Cooper up, but the lively winger is unable to keep his effort on target and drags his shot just wide of the right-hand upright.

Great atmosphere here and it is one of the reasons a lot of neutrals would want to see Portadown in the Premiership again because the home fans make a great atmosphere.

Stuart King has rolled the dice on 70 minutes as he throws on big Emmett McGuckin up top for Curtis Allen while Kyle Cherry is on for Luke McCullough as they move to a back four.

Conor Pepper sees yellow for a rash challenge on Len O'Sullivan wide of the penalty box.

Evan Boyce's whistle stops play, and Pepper accepts his punishment without protest.

Can Glenavon take advantage?

Summer signing Charlie Allen is introduced by David Healy for his second debut.

He replaces Chris McKee and receives a huge applause from the home crowd as he enters the pitch.

There has been a tactical change with Axel Piesold protecting the back three and Ronan Doherty has become a lot more advanced. He was given far too much space out on the right hand side and he has delivered a pinpoint cross and Shea Gordon just anticipates it and gets across the Glenavon defence and it's a great finish.

However, it is very much against the run of play, Glenavon have had opportunities and didn't take them and now this is a little bit of a sucker punch.

Jordan Gibson comes close to a hat-trick as he curls his free-kick just wide of the post.

Paul Heatley then volleys wide from a Carrick corner.

Glentoran threatening again from set pieces.

Centre-back Frankie Hvid heads goalwards from a corner at the back post, but just as the ball looks destined for the net it rebounds off teammate Jordan Jenkins' leg and into the welcoming arms of Aaron McCarey.

Some unnecessary afters from Ethan McGee and Niall Owens who are both told to relax and get on with the game by referee Ross Dunlop.
