Olympic 800m champion Rudisha out of Prefontaine

Kenya's Olympic 800m champion and world record-holder David Rudisha will miss the weekend's Prefontaine Classic Diamond League athletics meet due to a knee injury.

Rudisha's manager James Templeton said an MRI scan revealed the injury on Rudisha's right knee, reports Xinhua.

"The scan showed bruising of the bone and underlying ligaments," the organisers said in a statement Thursday. "Efforts today to test out the knee during a light workout did not go well, and Rudisha has had to withdraw from the Prefontaine Classic 800m."

Rudisha won the 800m at the Diamond League meeting in New York Saturday in 1:45.14.
