Sean Cavanagh's last minute point for Tyrone means the Red Hand County and Down must do it all again in Newry on Saturday in the Ulster Football Championship.
Second-half goals from Donal O'Hare and Conor Maginn had set Down up for victory, but Cavanagh's free at the death secured a replay for Mickey Harte's side.
The match finished 2-11 to 3-08.
In Connacht, a semi-final meeting with Mayo is the reward for Roscommon following their 1-18 to 0-13 win over Leitrim at Dr. Hyde Park.
In Leinster, it's Dublin next for Laois, who came through a potentially tricky tie in Aughrim, beating Wicklow by 0-21 to 1-11.
Wexford await Longford following their 0-19 to 0-15 victory over Offaly.
