Wikimedia 1968 Olympic Protest

The image of Tommie Smith and John Carlos raising their fists after the 200 meters at the 1968 Olympics remains one of the most iconic in sports history. But the third man on the podium, Peter Norman of Australia, is often overlooked as a bystander. In reality, Norman, who won the silver medal, had an integral role, and his involvement led his nation ostracizing him, a story that HBO explores on the latest edition of Real Sports.

"During the opening ceremony of the 2000 Olympics, all our greatest athletes did a lap of honor," nephew Matt Norman told HBO. "And he wasn't invited in any official capacity to do that."

Here is a clip from the report that premieres Tuesday at 10 p.m. ET/PT:

"Here's a white guy that had everything to gain if he just kept his mouth shut," Carlos said. "But he chose to stand for what was right. Peter Norman stands for what was right."
