Great Britain's men's wheelchair basketball team just failed to overhaul Australia in their opening match of the Paralympic World Cup in Manchester.
Simon Munn top-scored for Britain with 22 points
Australia had raced into a 23-8 lead by the end of the first quarter but Team GB then staged an impressive fightback.
A late rally took them to within four points but Paralympics runners-up Australia held on for a 56-51 win.
Britain women's team saw off Spain 34-24 in their opening game but then crashed to a 43-26 defeat to Japan.
Simon Munn led the British comeback against Australia with a game-high individual score of 22 points.
Munn said Team GB, who were bronze medallists at the Athens Paralympics, had been made to pay for their "tentative" start.

He added: "We want to win this tournament and although we lost it feels like a victory as we have learnt so much about the team."
The Visa Paralympic World Cup is former Australia coach Murray Treseder's first tournament in charge of the British team.
Britain's women began the tournament well, beating Spain before succumbing to hot favourites Japan, who had earlier also seen off France.
Sally Wager, who contributed six points against Japan, said Team GB had played well but added she expects to improve as the tournament progresses.
"We performed well but can definitely perform better," she said.
"We still have a lot to come and haven't shown our best yet. But I'm confident it will come together throughout the tournament."
