Internet Desk: World athletics legend Usain Bolt’s glorious career comes to an end and that too with a fashion which nobody would have wanted to see.
Gatlin, who has served two doping bans, and the US team also including another convicted doping cheat, Mike Rodgers, and Jaylen Bacon were booed when introduced although the jeering was less pronounced than for the individual 100m event.
A close first three legs saw Britain, the United States and Jamaica, seeking a fifth consecutive world title, level-pegged for the final leg.
But there was to be high drama as a visibly swearing Bolt pulled up in obvious pain, allowing the Japanese quartet to edge in for third.
The result means Bolt, 100 and 200m world record holder, finishes his career with 14 world career medals, one behind American Allyson Felix, to go with eight Olympic golds.
