Having enjoyed the high of his first World Cup goal, Leroy Fer could now miss the rest of the tournament with a hamstring injury.

The Norwich City midfielder headed in the Netherlands' opening goal of their 2-0 Group B win against Chile on Monday, but then limped out of training the following day.

Fer is now a doubt ahead of Sunday's last-16 clash with Mexico – and possibly beyond.

'The severity of the injury to the seven-time international's left hamstring should emerge over the next few days,' said a statement from the Dutch camp.

At least the news remained positive on Fer's Norwich future, which the midfielder maintaining he is prepared to be committed to the Canaries' Championship cause next season.

'We had a really disappointing season at Norwich and getting relegated was a bad moment for everyone at the club,' said Fer.

'For myself it's a difficult feeling to come away with Holland and forget about what happened at Norwich…but I am a Norwich player I am contracted to them for the next three years, so my commitment is to them.

'I am not thinking about anything else at the moment other than going back to Norwich.'
