Usain Bolt "was really cold" before pulling up with injury in his last championship final, according to his Jamaican relay team-mates.
Bolt's London finale ended in disappointment as he suffered a muscle cramp before the end of the 4x100m relay final which was won by Great Britain.
Yohan Blake said: "The race was 10 minutes late, we were kept 40 minutes. It was crazy.
"They were holding us too long."
Bolt had hoped to bring an end to his career with another two gold medals in London but leaves with only a bronze from last weekend's 100m.
And, seconds after taking the baton for Jamaica's anchor leg, he pulled up and tumbled to the floor with Dr Kevin Jones, Jamaica's team doctor, confirming Bolt had cramp in his left hamstring.
"It was 40 minutes and two medal presentations before our run," added former world 100m champion Blake.
"We keep warming up and waiting, then warming up and waiting. I think it got the better of us.
"It hurts to see a true legend, a true champion go out there and struggle like that."
110m hurdle champion Omar McLeod, who led out the Jamaican team which had won the 4x100m relay in each of the last four world championships, echoed the criticism of delays at the start of the final.
Mo Farah's lap of honour after his second place in the 5,000m final seemed to delay the schedule, with Farah also receiving his medal before the relay final.
"It's heart-wrenching," he said. "I gave it my all and I really wanted Usain to leave golden, or even if it was just a medal.
"It was ridiculous, man. We waited a really long time. I drank two bottles of water.
"But Usain Bolt's name will always live on."GB win gold as Bolt pulls up in 4x100m relay
100m champion Justin Gatlin called Bolt 'still the best in the world' after he won silver behind Great Britain, and also felt that the weather may have played a part in Bolt's injury.
"I think it was the elements (that caused the injury)," he said. "I'm sorry he got this injury. He is still the best in the world.
"This is farewell time, I am sentimental about it already now. In the warm-up area, we give ourselves respect and greeted each other. Usain Bolt is a great athlete."

'One season too many'
"I think it was just one season too many," said former Olympic champion Michael Johnson.
"I think Bolt was prepared to not win but I don't think he would have expected his last race to end like that. He would have wanted to cross the finish line.
"Even if he was just closing on the guys ahead - he wanted to give this crowd a show so they can say "I saw Usain Bolt run down the finishing straight."
"That was disappointing to see. We saw him in a way we have never seen before. In the 100m straining to try to finish and now we see him limping."
'How do you replace him?'
Former Olympic medallist Darren Campbell believes that Bolt's impact off the track is almost as hard to replace as his skill and records on it.
Bolt's charisma, charm and character have made him one of the most recognisable and marketable people on the planet.Usain Bolt last failed to win gold at the 2007 world championships
"Any stadium that Usain Bolt decides to grace ends up being full, that tells you all you need to know," Campbell said.
"What we are witnessing is so powerful, so inspirational, he can't be replaced. How do you replace him - as a sports star and a human being?
"Usain Bolt treats you the same whether you are a dignitary or the poorest man in the world. That's a unique skill.
"Whether he was a successful sports person or not, I think he would still have that flamboyant character. How do you teach that? I don't think you can."
