They took their goal-less run to seven games last night.
The Republic of Ireland will be among the third seeds for next month's World Cup qualifier draw.
Stephen Kenny's side failed to score for a seventh consecutive game - this time a goalless draw with Bulgaria at Lansdowne Road.
Robbie Brady hit the crossbar and Ronan Curtis missed a glorious opportunity, but it was a frustrating night.

But Kenny's charges have now gone more than ten hours of football without a goal.
The manager is backing his players after what's been a difficult run.
