Buzkashi (literally "goat grabbing" in Persian), also known as kokpar kupkari and ulak tartysh is the Central Asian sport in which horse-mounted players attempt to place a goat or calf carcass in a goal. It is the national sport of Afghanistan, although it was banned under the Taliban regime. Traditionally, games could last for several days, but in its more regulated tournament version, it has a limited match time.
