TEEN TOP's Ricky celebrated his 17th birthday on February 27th, but unfortunately, he did so with some back pain. During their performance of "Supa Luv" on this week's episode of SBS's "Inkigayo", Ricky worried fans when he was unable to complete his 'Matrix' move. It was later revealed that he had hurt his back during a recent rehearsal, and took painkillers before going on stage. Through their official Twitter, C.A.P wrote, "Today is Ricky's birthday, and even though his back hurts, he performed the move without saying anything. We hope that Ricky gets better soon and is able to show more impressive Matrix moves in the future." Ricky added, "Thanks to all that worried for me!!! I'll be working hard to get better." Because he's still in need of treatment, Ricky will be taken to a hospital for a check-up on the 28th.
