One Direction has issued a warning because fans are getting too excited at their concerts.
Niall Horan tweeted after the bands gig in Amsterdam last night. He thanked the crowd, calling them one of the loudest crowds yet, but also pleaded with people to limit what they throw onto the stage.
He says he was hit on the knee, causing him a lot of pain.
He's been recovering from major surgery which he had earlier this year and the singer claims he is 'very scared about it'.
