Canada suffered another surprise defeat on day two of the Wheelchair Rugby World Championship in Sydney.
The world number three ranked side lost to France in Pool B yesterday and were beaten again today by Poland.
It was a close contest but the European nation edged home 45-43 at the Quaycentre in the Australian city.
"It was a tough game, but we beat Canada - a big team with huge history," said Poland's Mateusz Wawczak, whose side were well beaten by Britain on day one.
"We're making big steps, improving a lot and going higher and higher.
"We are so happy we beat Canada today and we are waiting for another game tomorrow.
"It was our tactic to start as hard as we can and I think it was a good tactic.
"After you have the game on your side, you can control more.
"It was a perfect day for us."
Five teams remain unbeaten as group play continued at the Quaycentre and the Genea Netball Centre.
This includes Denmark, who have now won all three of their matches.
They beat neighbours Sweden in Pool A yesterday and were in action twice today, beating Ireland 56-47 and New Zealand 55-54.
