Big Time Rush's Logan Henderson was rushed to hospital after being injured on stage

Logan has now addressed the incident on social media, saying in a video shared to both the band's and his own Instagram Story: "Hey, Kraków, thank you for a great show. Sorry I couldn't stay to finish, I was having a little too much fun, so I hit my knee pretty bad and had to get taken to the emergency room."

The Boyfriend hitmaker reassured fans he will be better "in no time", though didn't clarify if he will be fit for the group's Big Time Rush in Real Life tour stops in Prague and Berlin this weekend.

He said: "I'm doing okay, and they're fixing me up, so I should be better in no time.

"It's gonna be good, we're gonna put some stitches in there, but anyways, thanks for tonight. Love you guys, and I'm doing all right, so thank you for checking in. Love you."

Big Time Rush - which also includes Kendall Schmidt, James Maslow, and Carlos PenaVega - shot to fame when they played fictional versions of themselves on four seasons of a Nickelodeon show of the same name.

They released three albums before taking a break after the programme ended in 2013 but returned to the spotlight in 2021, and have been playing every song from the Big Time Rush TV series on their current tour.

They said in a statement announcing the European gigs earlier this year: "We truly have the best fans in the world and when we sat down to plot this tour we wanted to give them everything they have always asked us for and dreamed of.

"That's the reason we are so excited to be going on the road all over the world to play every song from every episode of the TV show. We know how many of our fans hold these songs close to their hearts having first heard so many of them watching our show."
