Rudisha faces new injury concern ahead of worlds

Kenya's Olympic 800m champion and world record holder David Rudisha has been hit by another injury scare ahead of this summer's world athletics championships after he pulled a muscle in Ostrava.

Running in only his third race of the season in the Czech city on Tuesday night, Rudisha wobbled out at the start of his 600 metre race, holding his leg in pain.

"Very unfortunate that I pulled my muscle after 100m. But it is not a serious injury," tweeted Rudisha, who was looking to set a new world record in the little-run race.

"It's just a thigh muscle spasm... not serious problem. With few days of good care I hope to be back in training."

The injury is nevertheless a cause of concern for the 26-year-old runner, who has struggled to return back to his best form after battling a nagging knee injury which forced him to miss the 2013 world championships in Moscow.

Rudisha is now doubtful for the next Diamond League meeting on June 7 in Birmingham, where he set the fourth fastest 600m time in the world last August.

Rudisha's 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.
