Tokyo Governor Koike Yuriko suffered a fractured knee when she threw the ceremonial first pitch for a professional baseball game in the Japanese capital on Tuesday. The injury reportedly will take two months to heal.

The Tokyo Metropolitan Government said she performed the ceremony on Tuesday as part of a campaign to promote the World Athletics Championships and the Deaflympics due to be hosted by the capital next year.

After the pitch, Koike appeared to be walking with a limp and received a checkup at a hospital, which found an avulsion fracture of her left knee.

The government says she will carry out her duties remotely or over the phone, for the time being.
