A point nine minutes into injury-time earned Dublin an unlikely draw, while Armagh and Wexford earned wins in Saturday night's GAA action.
The real drama of the evening's football came at Croke Park where Monaghan, having led by nine points at half-time, were clawed back by the All-Ireland champions in the dying moments with the game ending in a 1-15 apiece draw.
Monaghan, who came into the encounter buoyed by a useful four-point win over Tyrone last weekend, started in blistering fashion at GAA headquarters with Conor McManus providing a good finish to hit the game's first goal inside the opening minute.
The Farney continued in a similar vein throughout the first-half, leaving Dessie Farrell's Dublin in their wake. Michael Bannigan and Ryan McAnespie contributed two points apiece, while Rory Beggan also came forward to kick a 45. Dean Rock (2) and Dan O'Brien were the sole scorers for Dublin during a bleak first 35 minutes.
Leading 1-9 to 0-3 at half-time, and with conditions at Jones' Road deteriorating, it looked as though Monaghan would kick for home. They padded their lead out to 1-14 to 0-8 with just over ten minutes of normal time left to play, but Dublin then clicked into gear.
Kevin McManamon's goal as the game headed for injury-time - six minutes was the allotted time by match referee Ciaran Branagan - gave Dublin hope at 1-15 to 1-12.
Dublin closed the gap to a point, but it looked as though Monaghan would cling on.
However, Branagan allowed one last play after Rory Beggan kicked a 45 wide, and it ended with Davy Byrne popping over the equalizer.

The point is enough to put Dublin out in front at the top of Division One, for a night at least.
Elsewhere, Armagh moved to the summit of Division Two with a 0-16 to 0-10 defeat of Kildare at the Athletic Grounds.
Despite a red card for substitute Jamie Clarke, who picked up a second yellow card early in the second half, Kieran McGeeney's side always held the upper hand.
In Division Four, goals from Ben Brosnan and Niall Hughes earned Paul Galvin's Wexford a 2-3 to 0-8 win over Waterford in Dungarvan.
