The 22-year-old playmaker suffered a broken vertebrae and will miss the remainder of the tournament after being struck in the back by Juan Zuniga’s knee.
However, Scolari tells Marca that Neymar feared much worse immediately after the incident.
“He said ‘I can’t feel my legs’,” Scolari says. “Marcelo was scared and called the doctor on, but the doctor couldn't get on in the confusion.
“It was a big shock, the image of Neymar being stretchered off to the helicopter, in difficulty, crying.
“Neymar was our benchmark, one of our references, because he is a player who makes a difference in any team. We're in a situation where we've lost something we don’t want to miss, especially for the semi-final and final.”
Brazil face Germany in the first semi-final on Tuesday, with Netherlands and Argentina battling it out in the other the following day.
