Eddie Jones joked that Owen Farrell had lost a piece of his nose after being flattened by an illegal challenge from USA openside John Quill.

Quill was the first player to be sent off in the 2019 World Cup after he caught Farrell with a shoulder to the jaw that sent the Saracens playmaker crashing to the floor and igniting a brawl.

Once referee Nic Berry had reviewed the incident and issued a red card, the USA had to play the final 10 minutes of their 45-7 defeat with only 14 men.

“I think we’re about to barbecue part of his nose – I think someone has found it on the field!” said Jones, who reported a clean bill of health following the game.

“We’ll have a short break and then focus on Argentina. We understand that they’re playing for their lives.

“They’re a passionate, proud rugby country so it will be important that we match their passion and play with a fair bit of control and with smarts about the game. They’re a difficult team to beat.”

The match was played in oppressive humidity that took its toll on handling.

“The conditions were difficult. It was 27 degrees and 80 per cent humidity,” Jones said. “You could feel it just by sitting in the grand stand, you had sweat dripping off you.

“The ball was hard to handle and there was maybe a period in the first half when we got seduced by the space and tried to play more of a passing game.”
