Dina Asher-Smith in Commonwealth Games doubt after injury scare in relay

• Fears of hamstring injury after Briton suffers sharp twinge
• Team GB's men win 4x100m bronze behind Canada and US

Dina Asher-Smith appears to be a major doubt for the Commonwealth Games after pulling up sharply during the 4x100m relay at the world championships in Eugene.

On a night when Britain's men's 4x100m team took bronze, Asher-Smith was also shooting for the podium as she powered around the final bend - only to then suddenly yelp in pain after suffering a twinge in her left leg.

Somehow she bravely hobbled the last 25 metres before handing the baton to Daryll Neita but Britain's chances of a medal had gone. Of far greater concern afterwards was the welfare of the 200m bronze medallist, who has looked so good at these championships.
