The increase in technology has also allowed many decisions in sports matches to be taken, or reviewed, off-field, with another official using instant replays to make decisions. In some sports, players can now challenge decisions made by officials. In football , Goal-line technology makes decisions on whether a ball has crossed the goal line or not. [43] The technology is not compulsory, [44] but was used in the 2014 FIFA World Cup in Brazil, [45] and the 2015 FIFA Women's World Cup in Canada, [46] as well as in the Premier League from 2013–14 , [47] and the Bundesliga from 2015–16 . [48] In the NFL , a referee can ask for a review from the replay booth, or a head coach can issue a challenge to review the play using replays. The final decision rests with the referee. [49] A video referee (commonly known as a Television Match Official or TMO) can also use replays to help decision-making in rugby (both league and union ). [50] [51] In international cricket, an umpire can ask the Third umpire for a decision, and the third umpire makes the final decision. [52] [53] Since 2008, a decision review system for players to review decisions has been introduced and used in ICC -run tournaments, and optionally in other matches. [52] [54] Depending on the host broadcaster, a number of different technologies are used during an umpire or player review, including instant replays, Hawk-Eye , Hot Spot and Real Time Snickometer . [55] [56] Hawk-Eye is also used in tennis to challenge umpiring decisions. [57] [58]
