Yesterday a rather distressing video of Niall appeared online from one of the shows in Amsterdam earlier in the week.

The clip shows Niall limping, clearly in severe pain. It’s just heartbreaking to watch. We’ve put the clip at the bottom if you wish to see it for yourself.

The reason for his limping is that someone had thrown something on stage at the boys and it hit Niall in the knee.

Of course many directioners know that Niall had a very serious operation on his knee earlier this year so it’s not the best idea to be throwing things at it.

Despite the injury, Niall took to Twitter to thank the fans, he said: “Amsterdam thank you for a great couple of shows! Appreciate you coming.”

He did then follow it up with a bit of a warning to any fans going to the upcoming dates on the ‘Where We Are’ Tour: “Also guys! Can you limit what gets thrown on stage please! Coz somethin thrown at me tonight! Hit my knee! A lot of pain from it!

“Never wana sound like I’m complaining! But only having my operation 5 months ago, I still get a bit of pain and I’m very scared about it.”

We know that the majority of you will agree with Niall on this one, but there will still be the ones that throw things on stage.

Now we’re pretty certain that you’d rather see all five boys on stage than just four of them while Niall is in hospital needing to have another operation because someone has ignored what he said and thrown something at his knee again.

So don’t throw things on stage!

What do you think of the clip?
