Breaking: Usain Bolt pulls up injured as Great Britain win the relay in London (Details, pics)

Usain Bolt received the baton with Jamaica in third, but halfway down his leg the towering sprinter pulled up clutching his left thigh, eventually doing a forward roll to the ground, to gasps from the 60,000 sell out London Stadium. The British quartet of Chijindu Ujah, Adam Gemili, Daniel Talbot and Nethaneel Mitchell-Blake claimed gold in 37.47 seconds, with the Justin Gatlin-led US four taking silver at 0.05sec and Japan wins the bronze.

However, he has officially retired from running in any major competition..

End of an Era for the Athletes legend.
