Phelps, the defending champion and world record holder who is heading into retirement -- again -- after Rio, finished second in a three-way dead heat with two of his greatest rivals -- South Africa's Chad Le Clos and Hungary's Laszlo Cseh.
Astonishingly, all three touched out in 51.14 seconds, behind Schooling's Olympic record 50.39.
Phelps, who now has 27 medals, had been hoping to win the event for the fourth successive Games.
