Is this the biggest AFL tackle in recent memory?

GWS Giants big man Shane Mumford absolutely flattened Geelong's Mitch Duncan in what could possibly be the biggest AFL hit of all time.

Duncan was chashing an overhead ball in the middle of the park when he was blindsided by the 200cm, 108kg ruckman.

The humongous hit left commentators gobsmacked, with many stunned that Duncan was able to get back to his feet.

"You don't come back from that", one said. "That leaves your brains scrambled for the rest of the day."
