The match officials have been confirmed for our Emirates FA Cup quarter-final ties, which take place across the weekend of Saturday 27 and Sunday 28 June.
With no replays at this stage of the competition, ties will go to extra time should scores be level at full time and would be decided by a penalty shootout if it remains level after that.
And a maximum of nine substitutes may be nominated, but only five may be used. In the event that extra time is played in any match, a club may use one
additional substitute player (a sixth in total) from the nominated nine substitutes, during extra time.
Details of each tie and the officials are below. Find out where you can watch the Emirates FA Cup quarter-finals on TV around the world.
