Lyles wins 200m bronze before Covid diagnosis revealed as Tebogo takes gold

• American star diagnosed with Covid before Olympic final
• Botswana star triumphs while Bednarek picks up silver

Letsile Tebogo has a nickname on the track and field circuit: the schoolboy. But over a dizzyingly unexpected Olympic 200m final the 21-year-old from Botswana graduated with honours as he took down the American pair Kenny Bednarek and Noah Lyles to claim gold.

His time of 19.46sec was staggering enough. That he did it while thumping his chest before crossing the line doubly so. Behind him was Bednarek, who ran 19.62, while Lyles could finish only third in 19.70 after appearing to struggle with the tight bends at the Stade de France track in lane five.
