MELBOURNE, Dec 24, 2025 (BSS/AFP) - Off-spinner Nathan Lyon is determined to fight his way back into the Australian team after undergoing surgery for a torn hamstring, coach Andrew McDonald said. The 38-year-old faces an extended period on the sidelines after damaging his right hamstring saving a boundary on day five of the third Ashes Test in Adelaide. McDonald said Lyon remained a key part of their plans as reports speculated that his 141-Test career could be over. It is the second serious injury Lyon has sustained in two years after being ruled out of the previous Ashes series against England with a calf injury picked up at Lord's in 2023. He had surgery on Tuesday, but was expected to be with the team during the fourth Ashes Test in Melbourne starting Friday.
