Why are Australia cricketers wearing black armbands in Test against India today?

Australia players are wearing black armbands today on the second day of the fourth Test against India in Ahmedabad. This is in tribute to Australia Test captain Pat Cummins' mother Maria Cummins, who passed away overnight. Pat Cummins had revealed that his mother had been battling a serious illness in recent weeks. She was diagnosed with breast cancer in 2005.
