in the event of a thunderstorm, within an eight-mile radius, the match would be halted with players removed from the field of play.
Supporters would be advised to take shelter in the stadium until the thunderstorm passes.
National Oceanic and Atmospheric Administration (NOAA) guidelines advise the match be halted and not restarted until no further lightning strikes have been detected within the eight-mile radius for 30 minutes.
If a lightning strike is detected, then the 30-minute timer would be restarted with the full time having to pass without any further strikes for the match to be resumed.
There is no limit on the length of the delay possible.
After the 30-minute period has passed, the players would then go through a 15-minute warm-up before the match would restart from the point it was halted.
