On Tuesday, the England and Wales Cricket Board (ECB) announced that the 37-year-old underwent an MRI which confirmed that he has suffered a calf injury. "As a result of the injury, he will commence a rehabilitation programme working with the England and Lancashire medical teams. He will be reassessed on an ongoing basis regarding his availability for the rest of Specsavers Ashes series," the ECB statement said.
England are already down after they lost the first Test by a massive margin of 284 runs. In Anderson's absence, it is highly likely that Joe Root will include debutant Jofra Archer in the playing XI in an endeavour to bolster their pace attack.
