It was a day of massive disappointment for fans and Sprint superstar Usain Bolt when he ended his illustrious career in agony due to injury while running the last lap of the 4x100m relay race in the World Championships.
Bolt, who was anchoring the Jamaican team, limped after running a few meters and fell down on the ground in pain, holding his head with both hands in dejection.
Bolt took the baton for Jamaica in third place but within a few strides he was on the ground, clutching his left leg, as host Britain secured gold ahead of the United States team which had Justin Gatlin.
Great Britain won the gold in 37.47 seconds while United States (37.52) and Japan (388.04) took the silver and bronze respectively.
The capacity crowd in the London Stadium was still digesting the shock earlier defeat for home hero Mo Farah in the men's 5,000m final, before Bolt's final disappointing appearance who limped out of the London Stadium arena.
"He didn't tell us exactly what happened but from what I saw, it looked like a strain or a cramp of some sort. He kept apologizing to us but we told him there was no need to apologize -- injuries are part of the sport," teammate Julian Forte told IAAF radio.
