Pentagon member Yeo One has been involved in a minor car accident, and therefore will halt his activities temporarily in order to focus on treatment for his injury. 

On February 10, Cube Entertainment revealed in an official statement, 

"Hello, this is Cube Entertainment.

We would like to notify that Pentagon member Yeo One will halt his activities temporarily due to a back injury.

On the early morning of February 9, the vehicle which Yeo One was riding in on his way home, after completing an individual schedule, was hit by a dunk driver. 

Immediately after the accident, Yeo One visited the emergency room, and the doctors found no major injuries. Although he should have returned home following his hospital visit to rest, Yeo One showed his strong desire to resume his schedules, and thus attended a live recording for 'IDOL LIVE: Homecoming Day' on the afternoon of February 9.

Then, on his way home after this schedule, Yeo One experienced pain in his back, and visited the hospital again. He has been treated accordingly and is now recovering. 

As a result, Cube Entertainment has determined that in order to prioritize the health and speedy recovery of our artist, Yeo One will halt his activities with Pentagon for the time being while focussing on his treatment. 

Additionally, Pentagon will promote as a 7-member group until Yeo One recovers.

Thank you."

Get well soon, Yeo One!
