Lightning has halted Collingwood and Melbourne’s match at the MCG midway through the last quarter.
Rain began falling heavily early in the fourth term, but a strong lightning flash was a cause for concern for the AFL officials on the bench.
Play continued for a further five minutes until players were forced from the field with Collingwood 41 points ahead.
AFL guidelines dictate that once a game is stopped for lightning it cannot resume for at least 20 minutes.
It is the second match at the MCG delayed by lightning this year, with Hawthorn and Geelong forced to the change rooms in the last quarter of their Easter Monday blockbuster.
Melbourne were already out of finals contention before the match started, while Collingwood were only a slight mathematical chance, having to smash the Demons by at least 100 points and rely on St Kilda shocking Carlton by a fanciful margin.
