World Rugby vice president Agustin Pichot has proposed moving the offside line two metres back and introducing Hawkeye technology to police it.
The former Argentina scrum half said the move would help to create more attacking rugby and using technology to help spot players encroaching the offside line would prevent officials from failing to spot transgressions.
Speaking to the Telegraph , he said: "We have technology so let's use it as they do in NFL.
"The referee has too much work to do working out what is going on at the ruck while the touch judges have a string of 12 players right across the pitch to judge on.
"Let's use the technology and that will soon sort it. Within five games, players will know that Hawkeye is watching them and they will stay back. That is my view.
"Or perhaps we should introduce a law that says players should be two metres behind the rear foot (of the breakdown).
"We have seen it at this World Cup that the space is at a premium. It is too defensive for my own personal liking. We have got to find a way to free it up."
Hawkye technology was developed in the UK by Paul Hawkins and is now used in a range of sports. The system was first used in the Premier League in 2013/14 as a way of checking whether the ball had crossed the goal line in controversial cases.
The system is also used in Aussie Rules and Gaelic football but has yet to be used for any code of rugby.
