Nico Pitney's Huffpost liveblog contains the following petition:
To the U.S. soccer team players:
Please consider wearing green wristbands in your upcoming match in the Confederations Cup finale. It would be a sign of solidarity and compassion for your fellow soccer brethren who were banned from the game they love and face unthinkable repercussions for simply adorning a green wristband symbolizing peace and freedom. This is not politics, it is human rights. Any slap on the wrist you may face from FIFA pales in comparison to what the Iranian soccer team faced, and what the Iranian people face.
Make us proud. Make the world proud.
