Usain Bolt crashed to the track in his final race with an apparent leg injury in the world championships 4x100m relay Saturday.
Bolt was anchoring the Jamaican team. He received the baton behind the U.S. and Great Britain but could not make up the deficit before losing his balance and falling to the frank.
The U.S. awon the women’s relay, giving Allyson Felix her record-breaking 15th career world medal to match Bolt.
In other events, Mo Farah, in the last championship track race of his career, lost a global final for the first time since 2011 with a silver in the 5000m.
