Portugal's Isaac Nader was a shock winner of the world 1,500m title when he thrillingly out-dipped Briton Jake Wightman on the line after defending champion and race favourite Josh Kerr suffered an injury mid-race on Wednesday.
Wightman, who has suffered terribly from injuries after winning the title in 2022, looked set for victory in a charge for the line but the race proved a metre too long for him as Nader snatched it by two hundredths of a second in 3 minutes 34.10 seconds.
Wightman took silver in 3:34.12 - Britain's first medal of the championships - with Kenyas 21-year-old Reynold Cheruiyot edging compatriot and namesake Timothy for bronze in 3:34.25.
