Irish boxers Paddy Barnes, Michael Conlan and Katie Taylor have all been given first-round byes in their respective Olympic divisions.
For Taylor, that means she is just one win from a medal and two wins from a gold medal bout.
However, the Bray boxer looks likely to meet fierce rival Queen Underwood in the quarter-finals.
Taylor’s father and coach Peter Taylor said: “It’s a tough draw but it’s tough for the [other boxers] too.
“It is great when you get fighters of this calibre coming together and it promises to be a great stage for amateur boxing.
“Katie does not feel under pressure at all. We are trying not to build it into a big event in her mind. As far as Katie is concerned once the bell goes it’s another fight – it could be the Olympic Games or a club show. She is going to do what she always does.”
Light-flyweight Barnes, a bronze medalist in 2008, is through to the last 16 and just two wins from a medal.
Barnes faces a possible quarter-final contest with fourth seed Serdamba Purejov, who won silver in Beijing.
Conlan is making his Olympic debut and he will start his challenge against Duke Micah or Jason Lavigilante.
Adam Nolan faces Ecuador’s Estacio Sanchez at welterweight while bantamweight John Joe Nevin takes on Dennis Ceylan of Denmark.
Darren O’Neill begins in the last 32 of the middleweights against Nigeria’s Muideen Akanji on Saturday [London-time].
After being beaten by Mark Barriga of the Philippines at the World Amateur Championships in Azerbaijan last year, Barnes had to secure his place in London through a qualifying tournament in Turkey in April.
John Joe Nevin will get Ireland’s campaign underway on Saturday (London-time) when he faces Dennis Ceylan of Denmark in his opening bout.
