The Australian men's wheelchair basketball team's Paralympic title defence was derailed by Canada's Patrick Anderson in the final in London on Saturday.
The outstanding Anderson finished with 34 points, 10 rebounds and eight assists as the north Americans prevailed 64-58 over the Rollers.
In a rematch of the Beijing final, Anderson managed to keep the heavily favoured Australian team at arms length throughout the second half.
It was a disappointing finish to the day after sprinter Evan O'Hanlon collected his second gold in the morning before Prue Watt maintained Australia's gold medal winning run in the pool.
Australia sit in fifth place on the medal table with only one day of competition to go with 31 gold, 23 silver and 29 bronze medals.
The nation has two gold medal opportunities on Sunday with Kurt Fearnley in the marathon and the men's wheelchair team taking on Canada in the final.
After winning the 100m earlier in the week, O'Hanlon maintained his dominance of the T38 class by winning the 200m in a world record time of 21.82 seconds.
"I came here and I've won 100 per cent of my races in world record time, the same as I did in Beijing," O'Hanlon said.
O'Hanlon, who has cerebral palsy, was never challenged on Saturday but admitted the race had hurt him.
"It's not that easy, I was feeling pretty ill afterwards," he said.
After a decade on the national team, Prue Watt collected her first Paralympic gold medal in the SB13 100m breaststroke.
Following the win, the vision-impaired swimmer revealed she was hoping to make the Winter Paralympic team in 2014 in Sochi in skiing.
"It has always been my dream to win a gold medal at the summer Paralympics and the winter Paralympics," she said.
"That has been a bit of a side project. I have been skiing a little the last couple of years at a national development level and I have skied since I was five.
"I am going home for two days and then I am going skiing for a week."
Watt will be targeting the slalom and giant slalom events.
Her win lifted Australia to 18 gold medals in swimming for the competition, double the team's return from Beijing.
Wheelchair racer Rheed McCracken, 15, continued his rise through the athletics ranks by collecting his second medal of the Games in T34 100m.
"Getting gold in Rio (in 2016) I think would just top my first two Paralympics off. Bronze, silver and then gold, that would be awesome," he said.
