"To get more women and more children playing rugby and I hope we did that around the world", she said.

Sonny Bill Williams' journey with New Zealand at the Olympic Games in Rio may have ended prematurely due to an Achilles injury, but he is remaining upbeat.

Williams appeared frustrated and was quickly assisted from the field without meeting the press following the end of the match.

"It is an exciting time for the rugby sevens team here in Rio", South Africa coach Neil Powell said.

As big an upset as their 15-man side's victory over the Springboks at the Rugby World Cup a year ago, Japan's win was their first in 16 attempts against the 12-times world sevens series champions.

But after watching the Australian rugby sevens women do what our blokes in the traditional game haven't been able to do for many years - beat New Zealand in a major final - I felt myself backtracking quicker than Daly Cherry-Evans after signing with the Gold Coast Titans.

"It's unbelievable, you never see a minnow team come here and beat a team supposed to be a gold medal contender".

Two James Rodwell tries put Britain in the driving seat, but Japan had no intention of rolling over, and they fought back to level the contest through converted scores from Lomano Lemeki and Katsuyuki Sakai.

"I'm just really proud of the girls". "Now we need to step up it's a must-win game for us against Kenya".

Britain, who kicked off their campaign with an impressive 31-7 defeat of Kenya, top pool C going into Wednesday's final opening stage match against New Zealand. "We were hopeful of gold and they were good enough to execute and play some really good footy".

Charlotte Caslick added salt to Kiwi wounds before consolation tries from McAlister and Woodman for a beaten New Zealand team.

Earlier, Ghislaine Landry had two tries and four conversions to lead the sevens squad to a decisive 33-10 win over Britain in the bronze-medal match as women's rugby made its Olympic debut.

Both finishing with one-win, two-loss pool records and five competition points, New Zealand finished with a points differential of +19, while the loss dropped the US to +18.

"When we saw Sonny Bill come off - that was a boost to us", he said.

The South Africans are in Pool B with Australia, France and Spain.

The celebration of the team's medal result extended back to Langford, where a collection of fans and officials that included hall of fame rugby player Gareth Rees of Victoria gathered to watch the day's games at the Fan Zone at the Westin Bear Mountain Resort.

"We thought if we kept moving the ball around, the big guys would tire somewhere, and they eventually did".
