Australian Jack Robinson has sent world No.1 John John Florence home from the Paris Olympics, riding tough in "super dangerous" surf to win their round-of-16 clash.
The much-feared break at Teahupo'o bared its teeth on Tuesday (AEST), forcing the women's heats to be called off for the day and a full postponement for Wednesday.
Robinson was dragged under at one point during his heat against Florence.
