Drogheda United remain second in the First Division after they were held to 1-1 draw at Tolka Park by 10-man Shelbourne.
A 90th minute penalty from Sean Brennan was enough for the Drogs to earn a point after Dayle Rooney had broken the deadlock with Alan Byrne sent off for the hosts in-between.
Drogheda United manager Tim Clancy made one change from the side that defeated Cabinteely on Friday as the previously suspended Lee Duffy replaces Richie Purdy.
In a first-half of few chances, Paul Skinner was called into action easy on as he denied Cian Kavanagh from point blank range.
Skinner was relieved to see referee Derek Tomney award a foul in his favour midway through the second-half after he dropped the ball under contact from James English.
Shels broke the deadlock on 73’ minutes as David O’Sullivan knocked the ball into the path of Rooney who blasted the ball high into the roof of the net for an emphatic opener.
The Boynesiders were given a lifeline just five minutes later when Alan Byrne was shown a second yellow card for a late foul on Conor Kane.
Buoyed by the man advantage, Drogheda dominated proceedings and they were given the perfect opportunity to level when Mark Doyle sprinted through on goal before being taken down by goalkeeper Dean Delany.
A considerable delay ensued with Shels manager Owen Heary dismissed but if didn’t affect Brennan who calmly slotted the ball into the corner for a previous share of the spoils.
Drogheda can go top of the table on Friday night when they face UCD at the Belfield Bowl.
