Tennis polo
The sport is played on a grass field between 80 and 100 yards long and 50 to 65 yards wide. The goal area is a semicircular line with an 11-yard radius and the penalty mark at 13 yards from the goal. An experimental rule has a second semicircular line on the field with a 17-yard radius. Generally, a field for gridiron football or soccer can be used.
College soccer
College soccer is played by teams composed of soccer players who are enrolled in colleges and universities. While it is most widespread in the United States, it is also prominent in South Korea and Canada. The institutions typically hire full-time professional coaches and staff, although the student athletes are strictly amateur and are not paid. College soccer in the United States is sponsored by the National Collegiate Athletic Association (NCAA), the sports regulatory body for major universities, and by the governing bodies for smaller universities and colleges. This sport is played on a rectangular field of the dimensions of about 64m (meters) - 70m sideline to sideline (width), and 100m - 110m goal line to goal line (length).
