JSF announced that Narumi Takahashi will pull out from the GP series (Cup of China and NHK Trophy) due to injury. Takahashi dislocated her left shoulder in April, during practice. She lost balance when doing a lift with partner, Mervin Tran.
The injury failed to improve, so Takahashi returned to Japan from Canada and was told she needs surgery. It would take around 3 months to fully recover.
Whether she will compete at Japan Nationals depends on the progress.
