There are usually 7 officials in hurling. A main referee follows the play around the field and has the final authority on decisions such as fouls, throws and card-issuing, un-disputable by players. The main play referee is assisted by two linesmen, who make decisions on who gains possession when the ball goes out of the field of play, and can also advise the referee on off-the-ball events such as a fight or an illegal tackle. As well as the referee and two linesmen, there are two umpires at each end of the field of play who stand on either side of the goal post and raise a white flag for a point, or a green flag for a goal respectively, also calling wides. Any umpire can also advise the referee on off-the-ball incidents, but does not hold as much authority as a linesman. At inter-county senior games and other important matches, an eighth official, the "Sideline Official", receive substitution notes and holds up the number of substituted players and the amount of [[Overtime (sports)|additional time]], similar to a soccer [[Assistant referee (association football)#Fourth official|fourth official]].<ref>{{Cite web|url=https://www.gaa.ie/my-gaa/match-officials/sideline-officials|title=Sideline Officials|access-date=2019-01-22|archive-date=2019-01-23|archive-url=https://web.archive.org/web/20190123071531/https://www.gaa.ie/my-gaa/match-officials/sideline-officials|url-status=live}}</ref> In recent times, technology called [[Hawk-Eye]] can be used if both the umpires and referee are unsure of whether a point has been scored or not, although this technology is not widely available.
