Azm fractured a bone in his left forearm on the second day of the first test at Lord's.
Pakistan batsman Babar Azam will miss the remainder of the two-match series against England after fracturing a bone in his left forearm on the second day of the first test at Lord's on Friday.
The 23-year-old righthander top-scored with 68 to help the tourists reach 350-8, a lead of 166, but retired hurt before the close of play after being struck by a Ben Stokes delivery.
"In that last session we took him off the field because he couldn't grip his bat properly, we treated him for pain," Pakistan physiotherapist Cliffe Deacon said in an interview on the Pakistan Cricket Board's official Twitter account.
"We decided to do a precautionary X-ray at the end of the day's play ... when we got to the hospital the X-ray confirmed that there was a fracture of the forearm, just above the wrist."
"Normally with these sort of fractures (recovery) varies between four to six weeks."
On the second day, Pakistan patiently advanced to 350 for eight against a toothless England attack to take control of the first Test.
Azhar Ali, Asad Shafiq, and Shadab Khan also made half-centuries in a solid batting display which left the touring side 166 runs ahead and in a strong position to go 1-0 up in the two-match series.
England, bowled out for 184, toiled on another overcast day at the home of cricket, dropping several catches in a sloppy performance which did little to lift morale following their heavy Ashes defeat and series lost in New Zealand.
Resuming on 50 for one, Azhar and Haris Sohail were untroubled by the England seam attack in the first hour and Azhar played one glorious cover drive for four off Mark Wood as the pair took the total to 87. Wood made the breakthrough when Sohail edged an outswinger to wicketkeeper Jonny Bairstow to depart for 39.
England captain Joe Root rotated his fast bowlers in an effort to unsettle the batsmen before turning to off-spinner Dom Bess in his first Test. Azhar nudged the 20-year-old for a single to bring up a half-century that included six fours, but the compact right-hand batsman failed to add to his tally, falling lbw to a full-length delivery from James Anderson.
Shafiq and Azam took Pakistan to 136 for three at lunch and the pair continued to gather runs comfortably in the afternoon session. Shafiq chopped Wood high over the slips to reach his half-century and moved on to 59 before he was surprised by a short ball from Ben Stokes which looped up off his bat to Dawid Malan at second slip.
Azam played some wristy strokes to reach fifty but he lost his partner Sarfraz Ahmed just before tea when the captain skied a pull off Stokes and was well caught by a diving Wood on the fine-leg boundary. After Azam was forced to retire hurt on 68, Shadab Khan and Faheem Ashraf played positively to extend their team's lead.
Shadab was badly dropped by Alastair Cook at second slip off Anderson before the experienced seamer bowled Faheem off the inside edge for 37. The 19-year-old Shadab passed 50 for the second time in his three Tests and was unlucky to be caught down the leg-side by Bairstow off Stokes for a valuable 52.
Hasan Ali was caught by Jos Buttler at gully off Anderson without scoring, but Mohammad Amir survived to the close unbeaten on 19 with Mohammad Abbas (nought) and Pakistan will bid to increase their lead before attempting to bowl England out cheaply again on day three.
