Following the tourists’ 360-run defeat, the Pakistan Cricket Board (PCB) announced on Wednesday that he had been sent for an MRI scan and that the team’s medical panel would evaluate the outcome.
On his debut at Perth Stadium, the 24-year-old claimed five wickets in a unit lacking in raw pace.
Pakistan’s attacking options are already severely limited because injured quick Naseem Shah is unable to play and Haris Rauf chose to play in Australia’s T20 Big Bash League.
Lyon took 2-14 as the visitors lost terribly, chasing 450 for the win. Josh Hazlewood and Mitchell Starc each claimed three wickets.
“The summer got off to a great start; everything clicked. We’ve played a lot of cricket, so the build-up was very chilled and relaxed,” Australia captain Pat Cummins said after the match. “No hiccups this week; it’s all gone to plan.
“500 Test wickets worldwide is incredible,” he continued, speaking of Lyon. “I am incredibly happy for him.”
Day four saw Australia declare at 233-5 in response to the hosts’ 487 after Pakistan was bowled out for 271 in their opening innings.
The second Test starts on Tuesday (Dec 26) at the Melbourne Cricket Ground.
