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.
CenturyLink Field
CenturyLink Field is also designed for soccer. The stadium meets FIFA sight line requirements and provides separate locker rooms for soccer teams. Camera locations were chosen for optimal television coverage of the sport. Numerous exhibition games have taken place at CenturyLink Field, including high-profile clubs such as Manchester United, Barcelona, Celtic, Real Madrid, Chelsea, Club América and Chivas de Guadalajara. These games have proved to be highly popular, and the first sell-out of 66,772 fans at CenturyLink Field was a soccer match between Manchester United and Celtic. National teams such as Brazil, Venezuela, Mexico, and China have played exhibition games at the stadium. The artificial turf has been temporarily overlaid with grass for international matches.
