Sergio Ramos was attacking for the ball with Salah, Salah wrapped his hand around him first to get the ball but unfortunately Salah started to fall, Which caused Ramos to fall after and Salah fell very bad on his shoulder while Ramos fell on his shoulder. 

Sergio Ramos never ever intentionally injure Salah. He should not be punished and 99% will not be punished.

UEFA + FIFA Should make a statement saying they will not punish him in any way as it was not intentional.
