The ‘Pink Test’ is an annual cricket tradition dedicated to raising awareness and funds for cancer treatment during the Sydney Test match in Australia.
The event pays tribute to Jane McGrath, the wife of former Australian cricketer, Glenn, who died in 2008 from breast cancer.
Jane was a prominent cancer support campaigner and established a foundation in 2005 to raise money to fund breast cancer care nurses in Australia.
Glenn is widely regarded as one of the best pace bowlers of all time. He took 563 wickets in 124 Tests for Australia and he was the most successful quick bowler in history when he retired in 2007.
England’s James Anderson and Stuart Broad have both surpassed him since, and he is seventh on the all-time list now.
This year’s event will take place on day three of the fifth Ashes Test between England and Australia.
The Test starts on 4 January (23:30 GMT, 3 January), so Jane McGrath day, will be on Tuesday, 6 January.
Australia lead the five-match series 3-1 and regained the Ashes after winning the first three Tests.
Day three of the Test sees players from both teams swapping their traditional caps for a pink version when they walk out onto the field.
During the game, the stumps will be painted pink and the players will have pink lettering and numbers on the back of their shirts.
Supporters are also encouraged to wear pink, while the Ladies Stand is renamed as the Jane McGrath Stand for the day.

Former fast bowler McGrath told BBC Sport that the occasion will be “special” for him and his family.
“This will be the 18th ‘Pink Test’ where we raise money in the name of my late wife Jane and last year we broadened the reach of the foundation to cover all types of cancer as well as breast cancer,” he said.
“It can be emotional but it is an occasion unique in sport given the scale – one that I view as a celebration of life.”
It has also become an annual tradition during a Test match at Lord’s for England fans and players to wear red in support of the charity founded by Andrew Strauss’ wife, Ruth, who died in 2018 from non-smoking lung cancer.
