A statement posted on the team’s Twitter account said that medical examinations conducted in Doha showed that Al-Shahrani’s condition was “stable” following “a forceful blow to the head, chest, and abdomen”.
He was then “transferred by medical evacuation to the National Guard Hospital in Riyadh” for an operation.
A follow-up statement on Wednesday night said the operation had been completed “with success”.
At the end of the match against Argentina, Al-Shahrani collided with Saudi goalkeeper Mohammed Al-Owais in stoppage time, which ended in a 2–1 upset victory for the Green Falcons.
Al-Owais’s left knee was fully aligned with Al-Shahrani’s face.
“I want you to make sure I’m fine, pray for me, and congratulations on winning,” Al-Shahrani said in a video clip from his hospital bed posted on social media.
Saudi Arabia won with a superb goal from Salem Al-Dawsari, ending Argentina’s 36-match unbeaten run.
Saudi’s next match is against Poland on Saturday.
