Tottenham's Vincent Janssen out of Netherlands' trip to Luxembourg - Sky sources

Vincent Janssen was taken off after 26 minutes after a knock to the head

Tottenham striker Vincent Janssen is out of Netherlands' World Cup qualifier against Luxembourg on Sunday after sustaining concussion, according to Sky sources.

The 22-year-old collided with Liverpool and Belgium goalkeeper Simon Mignolet in the 12th minute of Netherlands' 1-1 draw against Belgium on Wednesday.

Janssen attempted to play on for a further 14 minutes at the Amsterdam ArenA before being taken off in a disorientated state and replaced by Bas Dost.

After the game finished all-square, Netherlands head coach Danny Blind said: "Vincent is going to be a very difficult story.

"The physician told me it is a concussion. He lost 20 minutes of his memory and doesn't know what happened. We have to be careful with that and talk it through."

Mignolet tweeted after the game: "Wishing Vincent Janssen well after our collision. Would never intentionally hurt another player, but sometimes accidents happen."

Netherlands went 1-0 up through Davy Klaassen shortly after Janssen was substituted but drew 1-1 in the end following Yannick Carrasco's stunning late equaliser.
