Salah, who had been slated to carry Egypt's hopes at next month's World Cup in Russian Federation, then crumbled to the ground for a second time and was seen crying when he got up and then left the field to be replaced by Liverpool's England worldwide Adam Lallana.
Now the entire nation of Egypt holds its breath, hoping Salah will be healthy for the country's first World Cup appearance since 1990.
The Egyptian sports minister said on his Facebook page that "it is expected Salah will need 2 weeks for treatment".
However, Salah has taken to Twitter to appreciate the support he has received, while commenting on his World Cup future.
"It's a serious injury, a really serious injury", Klopp told his postmatch news conference. He is in hospital for an X-ray. It's either the collarbone or the shoulder itself. "It doesn't look good, that's it".
"He didn't play the final, we lost a very important player like probably Egypt lost a very important player".
It meant Jurgen Klopp's men finished the season without a trophy - marking the sixth consecutive campaign in which Liverpool have failed to claim silverware.
Spain kick off their Group B campaign at Russian Federation 2018 against Portugal in Sochi on June 15. "The shock of the boys was obvious".
"It was not the best script for us tonight".
"I don't know what would have happened if Mo could have played on, we will never know that".
