Full time: Donegal 1-23 Louth 0-18

The Ulster champions are through to the final four and Jim McGuinness' men will play Galway in the semi-final. 

That means Armagh are set meet the winners of Kerry v Derry, which is coming right up. 

A second point for Byrne, who has made an impression since coming on. 

Donegal then cancel that score out through Jamie Brennan. 

Not long on the field, Ciarán Byrne turns his man and shoots for the posts. 

Mogan has had a fabulous game and he chips in with another score for Donegal as we reach the 70-minute mark. 

Just the four minutes of additional time to play. 

Mulroy sticks another free over but the Wee County have left themselves with too much to do.

Thompson scores and Donegal are undoubtedly heading for the All-Ireland semi-finals as they lead by 10 points. 

Peadar Mogan has been a brilliant attacking outlet for Donegal at times today, and he has just got forward again to point. 

McHugh, who opened the scoring at the start of the match, adds another point. 

Sam Mulroy then sees his kick from the ground come back out off the post. 

A fourth point of the game from Tommy Durnin but that goal means Louth are now six back. 

Referee Joe McQuillan speaks to his umpires before awarding a goal to Donegal!

Eoghan Bán Gallagher finishes into the net from a couple of yards out after Patrick McBrearty had hit the post. 

The Wee County fans cheer their players on as another second-half substitute, Tom Jackson, makes his way into a central area from out wide before blasting over. 

Donegal concede a free in point-scoring range and Mulroy gladly accepts the invitation to add to his tally. 

Mulroy claims the mark and pops the ball over but Louth need a lot more of that. 

Shaun Patton's kick-out leads to a third score by Michael Langan and Donegal are in control here. 

Donegal open up a six-point gap as Ciarán Thompson is successful with an effort.
