Halifax dropped more points in the National League after conceding a stoppage-time penalty to draw 1-1 with lowly Brackley.
Will Harris had struck from a spot-kick of his own in the 88th minute to seemingly return play-off chasing Halifax to winning ways after Saturday’s surprise defeat to lowly Aldershot.
But during eight minutes of added time, the referee spotted a handball in the visitors’ penalty area and pointed to the spot for a second time.
Shane Byrne stepped up to equalise as lowly Brackley extended their unbeaten league run to seven games to remain four points clear of danger.
