Babar Azam is set to miss the remainder of Pakistan's tour of England due to a forearm fracture suffered while batting during day two of the first Test at Lord's.
Babar top-scored with 68 for the tourists but had to retire hurt midway through the final session after being struck just above his left wrist by a hostile short delivery from Ben Stokes.
The blow left Babar unable to hold his bat and a precautionary x-ray taken at the end of the day's play revealed the 23-year-old had suffered a fracture, sidelining him for up to six weeks.
Pakistan team physiotherapist Cliffe Deacon told the PCB Media Twitter page: "The fracture's in the forearm, one of the two bones in the forearm called the ulna.
"It is pretty much just above the wrist of his forearm, which is why he couldn't hold his bat properly.
"Normally with these sort of fractures (the length of recovery) varies between four to six weeks."
Babar was one of four Pakistan batsmen to register a half-century as they built a sizeable 166-run first-innings lead although he is highly likely to play no further part.
He will also be absent for the second and final Test at Headingley, which gets under way next Friday.
