A bit of pinball inside the box saw a United player accidentally flick the ball back with his own head, and it dropped to Jake O'Brien.
He didn't know much about it in his defence, and O'Brien could only steer an awkward header a few inches wide of the top corner.
It was very sloppy from United, who can only blame themselves.
