NU'EST's Aron injured his right thigh muscle a day before the group's comeback performance.

On the 13th KST, Aron was practicing choreography with his members for their showcase when he experienced pain in his right thigh. He was taken to the hospital, and after examination, they found that he had injured his muscle. He'll be visiting the hospital for a more thorough examination after the showcase.

A representative stated, "He's been given emergency treatment, so we think he'll be able to stand on stage. However, since he's still in pain, we plan to follow up with a closer exam."

Though he was able to perform a bit for the showcase, Aron's agency is not sure whether he'll be able to join for the group's 'M! Countdown' comeback performance. They're waiting for further details after his checkup.
