Niall looked noticeably annoyed as he walked away from the edge of the stage, poor guy.
As you'd expect, fans were plenty pissed off by the incident, with one Nialler supporter tweeting: "Cannot believe someone was that careless. Whoever u r, u could have killed him. Shame on u."
Meanwhile, someone hit Liam Payne on the head with a small object during a show - while he wasn't hurt, it looks like Louis Tomlinson helped out his pal and gave a stern look at the offending fan.
