Khawaja back spasm heralds Australia batting chaos

Usman Khawaja was unable to open for Australia after an ill-timed decision to leave the field to get treatment for back spasms just before England's first innings collapse on the opening day of in Perth leading to a hasty reshuffle of their top order.

After months of debate about Australia's batting order and the selectors' decision to reinstate Marnus Labuschagne at No. 3, he was forced to open anyway alongside debutant Jake Weatherald after Khawaja spent the last three overs of England's innings off the field as they lost 5 for 20 in 23 balls to be bowled out for just 172.

"I didn't know about it until the ninth wicket when he still had 10 minutes or so [to make up]," Mitchell Starc said. "We got caught off guard a little bit with the wickets falling pretty quickly in the back end there. It's just unfortunate that was the case. He'll manage that overnight and see how we're at tomorrow."

Khawaja, 38, had left the field several times in the first three hours of play and exited again with the score at 152 for 5 after 29 overs. Khawaja battled back stiffness through the day and had a back spasm the second time he left the field.

England then collapsed while he was stretching to overcome the spasm and it left stand-in captain Steven Smith calling for Khawaja to come back onto the field. Khawaja eventually did return to the field for the end of the innings but according to ICC rules had not returned for the equal amount of time he had been off and therefore was ineligible to open the batting.

"I don't think we really realised he wasn't going to come out at the start of the innings. It was probably more unsettling for the Aussies," Brydon Carse said after play.

It is understood Khawaja did not have a prior back injury. However, Khawaja did play 18 holes of golf on Thursday, having missed Australia's last optional training session, and also played several times earlier in the week. It is not unusual for Khawaja to play golf the day before a Test match. Scott Boland and Mitchell Starc, who took a career-best 7 for 58 on Friday, also played on Thursday along with several members of the coaching staff.

It meant Weatherald faced the first over from Jofra Archer, although he may have done so anyway. Weatherald had not faced the first ball of an innings in each of his last 20 first-class innings before his Test debut, during a run of form that saw him earn his first Test cap.

He was trapped lbw second ball by a searing full delivery from Archer that knocked him off his feet. His duck mirrored that of Nathan McSweeney's on Test debut for Australia when opening against India at the same ground 12 months ago in very similar circumstances.

Given the wicket fell so soon into the innings, it meant Smith walked out at No. 3 for the first time in a Test since 2017, although he had opened alongside in four Tests in early 2024 before returning to his preferred No. 4.

Khawaja made his way to the middle at No. 4 after Labuschagne fell to Archer after tea. Like a few in the top order, he didn't end up surviving long, gloving a superb delivery from Carse to the keeper for 2, as Australia followed suit in struggling with the bat and ended the day on 123 for 9.
