Rudisha withdraws from world championships with injury

LONDON (AP) David Rudisha has withdrawn from the world athletics championships.

The two-time Olympic champion confirmed his withdrawal on Monday via Twitter and will not defend his 800-meter title due to injury.

''It's sad and disappointing to announce my no show in the forthcoming (hash)london2017 WC due to a quad muscle strain,'' the 28-year-old Kenyan said.

The worlds start at the London Stadium on Friday.

Rudisha won gold in the 800 final at the same stadium in the 2012 London Olympics with a world-record time of 1 minute, 40.91 seconds .

Rudisha retained his Olympic title in Rio de Janeiro and would also have been the defending world champion in London, having won his second world title in Beijing two years ago.
