After his injury on the track, Bolt was comforted by his teammates and also by Twittterati who were full of praise for his running career.
The Jamaica team doctor says Usain Bolt had to pull up in the 4x100m relay due to cramp in his hamstring. We were waiting too long, and there was a hell of a walk as well.
Yohan Blake, who ran the third leg, said: "The race was 10 minutes late, we were kept 40 minutes".
But after tonight's triumph, he said: "2012 didn't go our way and we have been working hard since then".
"He's still the man, and this is farewell so we take our hat off to him, hope he gets well soon". "We were over warm". It was just insane and to see a true legend of the sport to go down like that, and we as Jamaicans and the world don't like to see that. They had star runners in their lineups like Yohan Blake, Omar McLeod and Julian Forte.
He said: "It's heart-wrenching".
"I couldn't believe it, I'm in shock, utter disbelief".
Panthers' Cam Newton (shoulder) throws in individual drills
Carolina is wisely being cautious with Newton, who's coming off surgery in late March to fix a partially torn rotator cuff. He attempted four passes on consecutive plays during red zone drills, according to Panthers.com's Bryan Strickland .
"It was ridiculous! We were there waiting".
The eight-time Olympic gold medalist didn't remain on the ground for long.
In the decathlon, two-time world champion Trey Hardee of the United States hit the third hurdle and clattered into the next one during the 110-meter hurdles to end his medal chances. Unfortunately it's one of those things, it's part of sport. His body can no longer hold up. "So it's just really insane".
Two years later, at the World Championships in Daegu, South Korea, Bolt showed his metal by winning the 200m after being sensationally disqualified from the 100m final for a false start.
Blake has not been able to train at full pace in the leadup to the race, which will be sprint great Usain Bolt's last on the track. And this is his farewell tour, his farewell race, so we have to take our hat off to him.
Fittingly, he will face Justin Gatlin and the United States in the final chapter of his unparalleled career.
He said: "You can't really have this night or championship define what he's done in the past".
It wasn't the fairytale ending that Usain Bolt or a lot of people wanted. "It feels like second nature because we work well together".
