A tackle is a fundamental action in sports like football and rugby, where a player tries to stop an opponent who has the ball. This is done by grabbing or bringing down the player with the ball to prevent them from advancing. Tackles can be executed in various ways, but they must be performed safely to avoid injuries. In American football, there are different types of tackles, such as the "open-field tackle," where a player tries to stop a runner in space, and the "wrap tackle," where the tackler wraps their arms around the opponent. Effective tackling is crucial for defense, as it helps regain possession of the ball and limits the opponent's scoring opportunities.
