It was a disappointing night for the USA's men's team as last-16 defeats for Raushee Warren and Errol Spence ended their hopes of a Boxing medal.

Fly Weight third seed Warren, competing in his third Olympic Games, lost 19-18 to Frenchman Nordine Oubaali in a nail-biting finish.

The 25-year-old said afterwards: 'I am still young. I gave my whole life to the Olympics and that was my dream. I have to work out what I am doing next.'

Spence, a Dallas-based 22-year-old, went out of the competition following a 13-11 defeat against third-seeded Indian Krishan Vikas in the Welter Weight division.

European champions Andrew Selby and Fred Evans extended Great Britain's fine start with last-16 victories in their respective Fly Weight and Welter Weight divisions.

Evans produced a fine last round to beat Egidijus Kavaliauskas 13-11 and Selby secured a 19-15 verdict over tough Kazakh Ilyas Suleimenov.

Belfast Fly Weight Michael Conlan clinched a straightforward 19-8 win over Ghana's Duke Micah.
