Sligo Rovers edged a point closer to clinching their first league title in 35 years as they played out a 0-0 draw with Cork City at Turner's Cross.
Ian Baraclough's Bit O' Red are now six points clear at the top of the table with three games to play. They host St. Patrick's Athletic next in a top-of-the-table clash on Saturday week.
Sligo enjoyed much of the ball in the first half but rarely threatened the Cork goal.
Cork had the game's best chances in the second half with Ian Turner bringing a save out of Gary Rogers before his corner was headed against a post by Kalen Spillane.
Shane Duggan then might have won it for Cork three minutes into added time but shot straight at Rogers.
Shamrock Rovers kept their faint hopes of qualifying for the Europa League via the league alive with a convincing 3-1 win over Bray Wanderers at the Carlisle Grounds.
Rovers started well and were 2-0 up at the break thanks to a superb free-kick from Killian Brennan on 17 minutes and skipper Ken Oman's bullet header from a Gary McCabe corner just past the half hour.
Kieran Marty Waters got Bray back into the game with a lovely goal on 56 minutes.
But Rovers responded to seal their win on 81 minutes. Bray defender Adam Mitchell was sent off for tugging back Gary Twigg to concede a penalty which McCabe duly blasted down the middle.
Bray boss Pat Devlkn was sent from the dugout for dissent in added time.
