Title rivals Linfield and Portadown fought out a dour draw at Windsor Park.
Michael Collins tussles with Linfield debutant Conor Downey
But Portadown manager Ronnie McFall complained that his side should have had a penalty in the second half.
"The television replay showed that Tim Mouncey clearly handled the ball. It was a blatant penalty. But we are in the frame for the run-in," he said.
New signing from Cliftonville Conor Downey made his debut for Linfield who went closest to scoring when Peter Thompson's low shot hit a post.
The title rivals may have each dropped two points but they were boosted by the news of leaders Glentoran's defeat at home to Dungannon Swifts.
The first half was a dreary affair but it ended with a moment of controversy when referee David Malcolm ruled that Ports keeper Kevin Pressman had picked up a Philip Craig backpass.
Portadown packed their goal to defend the free-kick and survived as Glenn Ferguson's effort was blocked out.
The best two chances came near the end with Thompson striking an upright and Portadown's Marc McCann forcing a save from Alan Mannus.
