Irish Premiership: Marcus Kane goal earns Glens win over Ports
A first-half goal from Marcus Kane gave Glentoran a deserved victory over Portadown, who had Keith O'Hara sent-off for a foul in the final minute.
Kane struck a right-foot effort past Billy Brennan from the edge of the box.
O'Hara was dismissed for bringing down Steven Gordon as he raced through on goal, while unused substitute Mark McAllister was red-carded for dissent.
In the first half, Allen's attempted lob went wide of the post, while Darren Murray fired wide at the other end.
