The capital looked to have it all wrapped up with a 7 point lead with 15 minutes to go but a Cillian O'Connor penalty at the death and a Diarmuid Connolly red card it was enough to drive the Connacht champions back into the game.
Michael Daragh MacAuley received a black card in the second half, when there was just a score between the sides but Dublin kicked on to extend their lead.
But it wasn't to be for Dublin and the sides will face off once again in whats expected to be next Saturday.
