Nairobi - Kenya's Olympic 800m champion and world record holder David Rudisha has pulled out of Sunday's Diamond League meet in Birmingham due to fresh injury fears.
The middle distance star wobbled out of a race in Ostrava late last month, holding his leg in pain.
"I just can't risk a race that soon. I am making good progress these last days but it will be just a few days too soon," the was quoted as saying the The Standard newspaper.
Rudisha, 26, is currently undergoing treatment in Europe. His coach said the injury "was just muscle spasm, which looked quite severe on television, but as we have established, it was not too serious."
Rudisha has struggled to return to form after battling a nagging knee injury which forced him to miss the 2013 world championships in Moscow.
His last memorable race was at the 2012 London Olympics when he stormed to a spectacular new world record of 1:40.91 in the 800 metres.
