Martins Indi will have to stay at the Mae de Deus hospital in Porto Alegre and could not travel with the team to the training base in Rio de Janeiro. He will fly back Thursday instead, reported Xinhua.
The defender, who played his 18th match for the Netherlands Wednesday, fell on his head after a foul by Tim Cahill. He had to be substituted just before half-time.
Dutch head coach Louis van Gaal said afterwards that a concussion means at least one week out of action. In that case Martins Indi will definitely miss the third group match against Chile Monday. This match will decide who will end as winners in Group B.
