Olympic 800m champion and world record-holder David Rudisha will miss the remainder of the season and is unlikely to race again until at least March, the Kenyan athlete’s coach has said.

Rudisha pulled out of next month’s World Championships in Moscow after failing to recover from a knee injury that will prevent him from defending his 800m crown.

His coach, Colm O’Connell, said: “His knee is actually already healing but Moscow came a bit too soon.”
