Canada won the Olympic Games gold in the men's 4x100 meter relay – after the USA messed it up with a faulty exchange.
The USA, without the covid-sick sprint star Noah Lyles in the team, was thus disqualified.
South Africa took the silver, and Great Britain the bronze.
The USA can console themselves with at least winning the gold in the women's relay. Superstar Sha'Carri Richardson sprinted in first across the finish line, just ahead of Great Britain in second place and Germany as the bronze medalist.
