Fearing farcical scenes at the Women's World Cup, football's rule-makers have agreed to an 11th hour request from FIFA to change the rules for goalkeepers on penalty kicks.

However, goalkeepers will still be penalised for jumping off their lines at the tournament, they just won't be yellow carded.

The combination of a no-tolerance approach to encroaching keepers and the use of video assistant referees has been met with much consternation in France.

Twice, players have missed penalties only to receive a second effort, after eagle-eyed assistants spotted goalkeepers straying from their lines by mere centimetres.

And both times they've scored on the second attempt, with ramifications for the competition.

In Rennes, France defender Wendie Renard scored the only goal of the game against Nigeria after botching her first effort, giving the hosts a 100 per cent record into the knockout stage.

On Thursday (AEST), Scotland were effectively knocked out by the rule, as Argentinian Florencia Bonsegundo netted a second effort in injury time to secure a 3-3 draw.

A 3-2 win would have lifted them above Nigeria on the ranking of third-placed teams and into the knockout rounds.

Instead the Scots, having blown a 3-0 lead, are going home.

FIFA have been criticised for trialling the rule at the tournament.

However, the governing body appealed successfully to the International Football Association Board to relax the mandatory yellow card as the tournament moves to the knockout stage.

That's because with the possibility of penalty shootouts comes the increased likelihood of goalkeepers being sent off for the minor offence.

As substitutions are banned during shootouts, the prospect of outfielders needing to put on goalkeeping kit and gloves to keep their side in the tournament was very real.

Hence FIFA refereeing committee chairman Pierluigi Collina moving to make a rare mid-tournament change.

"We felt that the risk for a second caution was a too high considering the number of penalties that are taken," FIFA

Collina gave his support to the use of the video assistant - most notably used in Australia's campaign to award the Matildas their winning goal against Brazil.

"I am very pleased that VAR (has) worked very well so far," he said.

"I have to admit though that a few mistakes were committed, and although it is something understandable, it should not have happened, and I regret that."
