The Daily Nation reported that the 27-year-old Olympic silver medallist was alone in his week-old Toyota Prado Sports Utility Vehicle when he was involved in a high-impact collision.

He was kept overnight for tests at Mediheal Hospital in Eldoret Town.

"I thank God to be alive," Yego told reporters as he left hospital with his wife Sincy and son Jarvis.

"Following the impact, I thought that I had broken my leg but I later discovered that I was okay."

The world champion had to cut short the interview after he was overcome by emotions.

Earlier, Yego had posted a message on Facebook, writing: "God is living and great! I'm OK my people. Can't believe am alive. @mungu yupo! I'm in stable condition."

A neurosurgeon at Mediheal Hospital, Florencious Koech, told the Daily Nation that the athlete’s life was out of danger.

 "He sustained soft tissue injuries following the mishap but he is now stable," he said.

"This will not affect his athletics career."

World 1500 metres champion Asbel Kiprop, who was involved in a similar accident on the Kabarnet-Iten road two years ago which resulted in his BMW X6 being written off, posted a message of support which also referred to another accident last week involving fellow athlete Andrew Rotich.

"What a stupid week," said Kiprop, the 2008 Olympic 1500m champion.

"Two days after Andrew Rotich got involved in an accident, Julius Yego tonight again got involved. 

"God protect us. 

"We thank God they are safe."

Yego won the world javelin title in Beijing in 2015 with a throw of 92.72m -  the best in the world since 2006.

Despite having to miss his last four throws because of injury at the Rio Games, Yego still did enough to take silver, which was Kenya’s first Olympic field events medal.

On Saturday (October 22) Yego, who also won gold at the 2014 Commonwealth Games in Glasgow, had told the Daily Nation that he was just beginning his build-up to the new 2017 season in which he hopes to defend his world title at the World Championships in London.
