Atletico Madrid striker Memphis Depay has suffered a hamstring strain.
Depay admits he pulled up short during Holland's win against Gibraltar.
He said, "I can't say much about the problem, I hope it's not that serious.
"It's not something I wanted and of course it's annoying. For me it's a difficult year, very tough mentally. It could be the toughest of my career.
"Unfortunately moments like these are part of the journey, I'll experience good things again."
