This sounds like the ultimate Fortean game. One has visions of a team of players, one leg apiece, hopping onto a pitch and, each time someone kicks the ball, he falls over. However, strange as it may seem, one-legged soccer has indeed taken off. After the 2010 earthquake in Haiti, there were a great many amputees who had a penchant for playing soccer and so they formed one legged teams and the game took off in the streets of the ruined cities. On one occasion, a one-legged team visited Texas.
The game is played in Sierra Leone as well.
Sometimes the player has an artificial leg as well as a real one, but not always. Some of them manage to support themselves on a set of crutches.
Strange what human endeavor can accomplish.
