Former Australia coach Eddie Jones is currently in intensive care after suffering a stroke.
The 53-year-old, who is currently the coach of Japan, is said to have complained of a headache on Tuesday night after returning to the Brave Blossoms' training camp in Tokyo.
Former South Africa coach Jake White is quoted by The Guardian as saying: "He is in intensive care and he currently doesn't have movement on his left side but he is talking, and typical of Eddie, it's about the challenge of the All Blacks and the subsequent European tour. My understanding is he will be in intensive care for at least the next week."
Jones had been preparing for a match against the All Blacks on November 2.
