Aidan Walsh will be looking to get Team Ireland back to winning ways and to move within one win of a medal in Tokyo on Tuesday morning.
The Belfast man enters the ring in the Kokugikan Arena hoping to bring an end to three Irish defeats on the bounce.
The slick mover will have to put the disappointment of his sister, Michaela Walsh’s Olympic exit and defeats to teammates Brendan Irvine and Emmet Brennan behind him as he makes his Olympic debut.
The Monkstown BC boxer takes on Cameroonian Albert Mengue Ayissi, who beat Thabiso Dlamini in the round of 32, in the last 16 of the 69kg class.
Walsh is due in the ring at 3:30 am [Irish time].
