Australian featherweight Skye Nicolson will continue her push towards a breakthrough Olympic boxing gold on Wednesday after compatriots Caitlin Parker and Paulo Aokuso both lost in the round of 16.
Aokuso was pipped in the tightest of light heavyweight contests with Gazimagomed Jalidov Gafurova, the Spaniard convincing three of the five judges enough to progress to the quarter-finals.
Aokuso dominated the second round 5-0 but lost the third 4-1, the win ultimately decided by a 3-2 first round awarded to the Spaniard despite the Australian landing several solid blows.
Earlier Parker was beaten 5-0 by Panama's Atheyna Bylon in the women's middleweight division.
Nicolson is still standing though, and a win in Wednesday night's quarter-final against Great Britain's Karriss Artingstall will guarantee Australia it's first boxing medal since 1988, given both semi-final losers are awarded bronze.
The 25-year-old Queenslander is following in the footsteps of her late older brother Jamie, who boxed for Australia at the 1992 Olympics.
Skye's brothers Jamie and Gavin tragically died in a car accident while en route to boxing training in 1994, a year before she was born.
