In many sports, midfield is the part of a sports field that is near the line that is equally far from the end lines. That is, in American football it is the part of the field near the 50-yard line; in association football (soccer) and field hockey it is the part of the field that is between but roughly equally far from the two goalies. In association football, a player who is a "left midfieler", "center midfielder", or "right midfielder" plays much of the game in the midfield, whereas an "attacker" or "forward" plays closer to the opponent's goalie and a "defender" or "back" plays closer to the player's team's goalie.
