A "flanker" is a position in the sport of rugby, specifically in rugby union and rugby league. Flankers are typically positioned on the sides of the scrum and are responsible for both defensive and offensive plays. They are known for their agility, speed, and ability to tackle opponents effectively. In rugby union, there are usually two flankers on each team: the blindside flanker and the openside flanker. The blindside flanker plays on the side of the scrum that is closest to the touchline, while the openside flanker operates on the side with more space. Both flankers play a crucial role in supporting the forwards and securing possession of the ball.
