TOPSHOT-ATHLETICS-WORLD-2017

TOPSHOT - A combination of pictures created on August 13, 2017 shows Jamaica's Usain Bolt pulling up injured and rolling on the track in the men's 4x100m relay athletics event at the 2017 IAAF World Championships at the London Stadium in London on August 12, 2017. Usain Bolt's glittering career swansong came crashing to an end when he pulled up injured 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 the finishing straight 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.
