With England only needing to lose by less than 16 points, both teams were set to benefit from the clock running down.
"Unique. Bizarre. Controversial," wrote the official World Rugby Sevens Twitter account. "Time seems to stand still in Toulouse as England deliberately delay scoring the try that takes them through to the quarter-finals – and Argentina, down to six men and also going through, let them."
"It might be gamesmanship, but this is the laws," remarked commentator Rob Vickerman."Quite remarkable scenes."
Many fans weren't impressed, with some calling for England and Argentina to be banned as a result of the scenario, while others suggested that it bordered on match fixing.
Journalist Paul Tait suggested the referee could have stepped in. "England should have been penalised. The referee knows better. Law 9.7.d wasting time. Law 9.27 against the spirit of good sportsmanship."
EK Rugby Analysis wrote: "Obviously don't like seeing this. Rationally, it makes sense for England and Argentina as they both go through while conserving energy – Sevens is exhausting to play. There should be something like a 30s time limit to score though similar to conversions and pens."
