• Officials will calculate heat stress risk index before play at MCG
• Extreme heat policy allows for additional drinks breaks during Test

Cricket Australia is advising fans to prepare themselves for hot weather at the MCG on Boxing Day, as the Bureau of Meteorology forecasts the temperature reaching 40C in Melbourne on the first day of the fourth Border-Gavaskar Test.

CA’s chief of cricket James Allsopp said the forecasts had been changing, but that “it is looking hot” and his organisation would ensure appropriate messaging is used in the coming days.
