Rules and play
Players are permitted to play the ball with any part of the stick other than the rounded side (back). The flat side is always on the "natural" side for a right-handed person — there are no "left-handed" hockey sticks (for actual use in play, some have been made as novelties).
Positions
Teams consist of eleven players on the field, and up to five substitutes. Substitutions are not limited but may not be made during a penalty corner. There are no set positions (even a goalkeeper is not required under the 2007 rules), but most teams arrange themselves (in a similar way to football (soccer) teams) into fullbacks (defence), midfielders (halfback) and forwards (front line)). Many teams include a single sweeper. The rules do not specify a minimum number of players for a match to take place, but most competitions have some local ruling on this, with seven players being a common minimum
One player from each team may be designated the goalkeeper. Goalkeepers must wear a suitable helmet with full face mask and are also permitted to wear protective padding, including large leg guards, kickers and gloves. Although goalkeepers may block or deflect the ball with any part of their bodies, and propel the ball with their feet (and from 2007 any other part of their equipment in a "goal-saving action"), they must always carry a stick, and normal stick rules apply. Goalkeepers are permitted to play the ball outside their defensive circle (scoring area or "D"), but must only use the stick in this circumstance. |

General play
For the purposes of the rules, all players on the team in possession of the ball are attackers, and those on the team without the ball are defenders.
The match is officiated by two field umpires. Traditionally each umpire generally controls half of the field, divided roughly diagonally. These umpires are often assisted by a technical bench including a timekeeper and record keeper.
Prior to the start of the game, a coin is tossed and the winning captain can choose a starting end or start with the ball. The game time is divided into two equal halves of 35 minutes each, with five minutes for half-time. At the start of each half, as well as after goals are scored, play is started with a pass from the centre of the field. All players must start in their defensive half, but the ball may be played in any direction along the floor. Each team starts with the ball in one half, and the team that conceded the goal has possession for the restart.
Field players may only play the ball with the face of the stick. Tackling is permitted as long as the tackler does not make contact with the attacker or his stick before playing the ball (contact after the tackle may also be penalised if the tackle was made from a position where contact was inevitable). Further, the player with the ball may not deliberately use his body to push a defender out of the way.
Field players may not play the ball with their feet, but if the ball accidentally hits the feet, and the player gains no benefit from the contact, then the contact is not penalised. Although there has been a change in the wording of this rule from 1 January 2007, the current FIH umpires' briefing instructs umpires not to change the way they interpret this rule.
Obstruction typically occurs in three circumstances - when a defender comes between the player with possession and the ball without first performing a legitimate tackle; when a defender's stick comes between the attacker's stick and the ball or makes contact with the attacker's stick; and also when (usually deliberately) blocking the opposition's passage to the ball (called third party obstruction).
When the ball passes over the sidelines, it is returned to play with a sideline hit, taken by a member of the team whose players were not the last to touch the ball before crossing the sideline. If it crosses the backline after last touched by an attacker, a 15 m hit. A 15 m hit is also awarded for offenses committed by the attacking side within 15 m of the end of the pitch they are attacking. |
