LONDON, United Kingdom (AFP) — Usain Bolt’s glittering career swansong came crashing to an end when he pulled up on the anchor leg of the world 4x100m relay won by Britain on Saturday.

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 a surprise bronze (38.04).
