Instructions
Position the defensive player you are controlling as close to the offensive player as possible. Avoid making contact with the offensive player, as this could incur a pass interference penalty, which would negate an interception.
Move the defensive player toward where the ball is heading when you are in the vicinity of the offensive player.
Press and hold the "Y" button if you are playing on the Xbox 360 or the triangle button if you are playing on the PlayStation 3 as the ball arrives. Alternatively, if you are playing on the Wii, push the top part of the Wii controller up and then quickly pull it toward you. Your player will go for the interception rather than just swatting the ball.
