Just how far will Oracle go to keep the America's Cup?

They are allowed to have two boats in racing, while Team New Zealand's allowed just the one.

And former French skipper Bruno Trouble told Mike Hosking that's stoking fears Oracle could sacrifice one of them in a collision to get ahead.

The America's Cup Hall of Fame member said it might be the only thing Oracle can do.

But he thinks sportsmanship should stop it from happening.

Team New Zealand's currently ahead 3-nil in the race to 7 wins. Racing resumes on Sunday.
