Neymar in doubt for World Cup semifinals after injuring his back in match against Colombia

Brazil coach Luiz Felipe Scolari says Neymar may not be able to play against Germany in the World Cup semifinals because of injury.

Neymar was kneed in the back in the 2-1 quarterfinal win over Colombia on Friday. He was crying in pain as he was carried off the field after a collision with Juan Zuniga.

The Brazil striker was taken to a private clinic.

Scolari says "it will be very difficult for Neymar to play" on Tuesday in Belo Horizonte.
