It's so easy for Jason McGee but no, he's missed when it looked easier to score!

He had done all the hard work but his kick is wide of the upright.

Conor Laverty is being calmed down on the sideline by the officials. He's been bouncing up and down the touchline from the first throw in!

Level once more. Guinness makes amends for his earlier miss as he splits the posts!

And Ciaran Thompson capitalises! Donegal lead by one early in the second half.

Caolan Ward actually got a crucial touch to take the sting out of Guinness' effort. What a block!

Off the line! Eoghan Ban Gallagher saves Donegal after Daniel Guinness broke through!

Big let off!

Right, off we go!

Remember, we have to have a winner this afternoon. There's no replays in this year's Championship.

It's hard to say who has been the better team, but if I was Down I'd be happy enough with the first half performance.

Do you think Liam Kerr enjoyed his goal?

There is a bit of desperation for both teams today and that desperation is perhaps leading to those snapped efforts.

It's been poor, to be honest. You have to take into consideration they are very defensive teams.

Donegal's decision making has been very, very poor. That's right across the piste. Defensively they have been solid but Down have been able to penetrate them from time to time.

Now Eugene Brannigan, in his long socks, tries to put Down ahead at half-time but it fades wide of the post.

And there goes the half-time whistle. All level.

Patton tries to repeat his earlier effort but it drifts wide. Will there be one final score before the break?

We're going to have two minutes of additional time.

And we're level once more as Shaun Patton splits the posts with a 45.

It's not the most high scoring of games but it's tight!

There's another bit of quality as Ryan Johnston lands a swerving, dipping score to put the hosts back into the lead.

Someone obviously didn't fancy paying for tickets or wanted a bird's eye view of the game and is flying over the ground in a low-flying plane.

That's the constant drone in the background you can hear on TV, don't adjust your sets.

Here's how Liam Kerr levelled for the hosts!

Great finish!

Niall Kane with a massive save to keep out Conor O'Donnell.

Niall McParland sticks out a leg to to deny Ciaran Thompson on the follow up with Down goal unguarded.

How pivotal will that be?
