• All-Ireland 'round-robin' stage removed
• Hurling handpass rule defeated
• Minimum club appearances before county withdrawn
• Adding replays into provincials finals & adjusting then in All-Ireland finals withdrawn

It's been a slow start to the defence of the Division One title for Derry while Ulster Champions Donegal have been in imperious form thus far.

Here's how the table looks ahead of today's games.

Today's meeting between Armagh and Mayo is crucial for both sides in terms of their outlook for the rest of the league campaign.

With the two teams each on two points through three games, the winners can begin looking up the table, whilst the losers will be left in a perilous position.

Armagh's start to the season hasn't been helped by a long injury list, but there is good news with Paddy Burns, Connaire Mackin and Rory Grugan returning to the side. However, Greg McCabe misses out having picked up a groin injury during the week. He drops out alongside the suspended Aidan Forker and Gareth Murphy from last week's defeat at Donegal.

For Mayo, Ryan O'Donoghue replaces Cian McHale from the team which defeated Tyrone. Aidan O'Shea was listed to start, but instead Paul Towey keeps his place.

Armagh: E Rafferty; T McCormack, B McCambridge, P Burns; Connaire Mackin, J Duffy, R McQuillan; B Crealey, N Grimley; J Hall, R Grugan, D McMullen; C Turbitt, A Murnin, O Conaty.

Mayo: C Reape; E O'Donoghue, D McHugh, E Hession; S Coen, D McBrien, E McLaughlin; C Reid, M Ruane; D Neary, F Irwin, J Flynn; P Towey, D McHale. R O'Donoghue.
