Cummins out of last two Ashes Tests; Richardson, Murphy in Boxing Day Test squad

Pat Cummins has been ruled out of the remainder of the Ashes. The 32-year-old missed the first two games but featured in the third in Adelaide, after rehabilitating for a back stress injury. With the series pocketed 3-0, Cummins has been afforded rest for the last two fixtures - something he'd hinted at in the press conference after the Adelaide fixture. Fast bowler Jhye Richardson and off-spinner Todd Murphy have been added to the squad for the Boxing Day fixture.

"He won't play any part in the rest of the series," Australia coach Andrew McDonald told reporters on Tuesday. "That was a discussion that we had a long time out around his return. Yeah, we were taking on some risk. We've now won the series, and that was the goal. To position him for further risk and jeopardise him long term is not something that we want to do.

"Pat's really comfortable with that. If he had any setback in the build-in as well, we would have shut him down straight away," McDonald added.

Steve Smith should return and lead the team in Cummins's absence, pending his recovery from an inner-ear issue that sidelined him in Adelaide.

Australia will also be without Nathan Lyon. Cricket Australia confirmed that Lyon needs surgery after having torn his right hamstring during the third Test in Adelaide. The injury occurred when he dived to save a boundary on Day 5. Murphy is now in line to make his Test return at home after last playing the format in Sri Lanka in February this year.

If chosen to replace Cummins, Richardson could end a four-year wait to play a Test again, having last played in Ashes 2021. He underwent his third shoulder surgery earlier this year and has been training with the team through the first three Tests, gradually increasing his bowling loads. Earlier this month, Richardson showed his readiness by bowling 26 overs and picking a five-wicket haul against England Lions.
