Did Liam sprain his wrist?

Back in September, One Direction (sans Harry Styles, who was still underage) celebrated Niall's 21st birthday in Las Vegas! While dancing the night away, Liam might've gotten a little too into it… while busting a move on the dance floor, he injured his arm and ended up in the emergency room! When a photo of Liam sporting a cast surfaced on twitter, fans asked his BFF, Andy Samuels, for an update. "We decided to break dance and he got carried away. You know how it is haha," he tweeted. Yikes! No worries though Liam managed to recover in time for 1D's epic iHeartRadio performance!
