Raffaele Cretaro skied an injury time penalty as Finn Harps picked up a vital point in their quest for survival, following a flat north west derby at the Showgrounds. The Sligo veteran fired his spot kick over Richard Brush's crossbar after Craig Roddan won a penalty following a challenge from Ethan Boyle.
This was the Bit O'Red's third scoreless draw on the bounce following a game in which they deserved to take the points.
Rovers went into the game looking to earn their first competitive win over their neighbours in six seasons with Harps having the better of the results between the two sides this year. While Ollie Horgan's men were looking to end a horrendous run of nine games without a league point since a win over Galway in July.
Brush had to be alert early on to see a free a piece from Achille Campion and John Russell go past his posts. While Ruairi Keating could only blast over on nine minutes when the away side manufactured their first opportunity of the tie.
Jimmy Keohane, deputising at left back for Rovers glanced wide from an advantageous position on 13 as both camps battled for dominance.
The Ballybofey men were forced into an early change when Keating limped off having sustained a knock on 25 minutes. The Westport man was replaced by Ryan Curran who was involved in the game's next talking point when he collided with Rovers net minder Ciaran Nugent inside the Sligo area just short of the half hour. Referee Derek Tomney however deeming no foul play.
Rovers centre half Pat McCann was offered a decent chance nine minutes from the break when Achille Campion skipped past Damien McNulty to square for the American. He however skewed his effort from a goal-scoring position as the ball rolled to safety.
Raffaele Cretaro tested Brush two minutes later following a swift Sligo counter as Dave Robertson's charges finished the opening half the stronger. While Brush was on hand to deny his former employers once more before the break as he pulled off a great reaction save to deny Campion after the prowling Parisian latched on to Daniel Kearns' corner.
Harps' Sean Houston may count himself a little lucky to see out the half after a strong challenge on Liam Martin in injury time. Tomney deciding that the Letterkenny man's robust tackle was not reckless enough to warrant a dismissal.
The away side started the second half with a flourish and went close to breaking the deadlock three times within the same minute. Nugent had to be alert to keep out Packie Mailey before some desperate defending from Tobi Adebayo-Rowling kept Harps at bay seconds later. While Martin swept Adam Hanlon's low drive from the line from the resulting corner.
Martin skied his effort from 25 yards with Brush back-peddling just past the hour before Curran and Campion wasted opportunities at either end.
Michael Funston flashed a chance past Nugent's right hand post from the edge of the Sligo box, following a recycled Gareth Harkin free 15 minutes from time.
Nugent threw himself on Damien McNulty's speculative effort from the angle with four minutes remaining before Cretaro blew his chance to win the game late on.
