MAMAMOO's label posted, "Whee In twisted her ankle on the stairs last night on December 27, while heading home from her schedules. According to the doctor, there are no serious contusions, but the area can still suffer from overuse and so [Whee In] was ordered to wear a protective cast."
The label continued, "We felt that it would be difficult for Whee In to attend MAMAMOO's schedule in Vietnam today (December 28), but Whee In clearly expressed her wishes to greet her Vietnamese fans, and so she will be accompanying us. She has no physical issues outside of her ankle injury, and her condition is good overall, so due to doctor's advisory Whee In will perform sitting on a chair."
MAMAMOO are expected to perform at the upcoming 'KBS Gayo Daechukje' and the 'MBC Gayo Daejejun' on December 28 and December 31.
