Cillian McDaid puts Galway ahead just before the break, and somehow, despite being dominant for most of the first half, Armagh trail at the interval.

Kieran McGeeney is forced into a change with Joe McElroy having to go off. Tomas McCormack comes on in his place.

Rob Finnerty pops over a close-range free to bring the sides level. Galway are restored to 15 players.

Galway need a spark, and Padraic Joyce has turned to his bench after 27 minutes to introduce Matthew Tierney and Cillian McDaid. Daniel O'Flaherty and the previously cautioned Kieran Molloy make way.

Andrew Murnin is having himself a game in midfield again this week. He fetches the Galway kick-out and sets Cian McConville on his way to fist over and stretch Armagh's lead out to three.

Kieran Molloy is lucky not to receive a black card as well. He nailed Joe McElroy after he had laid the ball off. Referee Barry Cassidy opted to show him a yellow, stating that the timing of the hit was close to the ball being slipped.

Galway are reduced to 14 men with Ciaran Mulhern receiving a black card after 23 minutes.

Terrific strike from Oisin O'Neill to restore Armagh's lead after Finnian O Laoi had brought Galway level.

Ross McQuillan points his second of the game to get Armagh back on terms before Oisin O'Neill fists over to nudge the home side in front.

Armagh are dealing well with Galway attacks. Oisin Conaty and Fergal O'Brien extended their lead, but Fionn McDonagh has pulled a score back for the away team.

After hitting six points from play last weekend against Monaghan, Conor Turbitt is back on the scoresheet to put Armagh in front.
