In cricket, a substitute is a replacement player that the umpires allow when a player has been injured or become ill, after the nomination of the players at the start of the game). The substitute can act for the injured or ill player in the field, although they may not bowl, bat, or act as captain, unless otherwise agreed by the captains). The substitute is generally called the "12th man" and is listed on the team sheet as the first player outside the starting XI. The 12th mans additional tasks include bringing on drinks at scheduled breaks and supplying batsmen with anything else they might need while out in the middle, such as new gloves or a change of bat. The substitute must wait until the end of an over before entering the field of play. The batting team can never make use of a substitute, and should a batter need to leave the crease for medical attention, they will simply leave the field and the next batter comes in. The substitute is not required to be a particular player before the start of the match, and can be anyone, providing the umpires approve the use of a substitute).
