Newcastle had the lead with 1-0 against Sydney FC in the Australian top league in football.
But when the post from Sydney striker Trent Buhagiar was to be cleared away, the home team's defender stood in the way.
Newcastle's Connor O'Toole's could easily have steered the ball outside the goal but hit teammate Nigel Boogaard in the chest and thus Sydney had equalized to 1-1.
