Jacob Umaga called up by Eddie Jones for England internationals

"With nine players out injured, it does create some opportunities for the younger guys to show what they can do. He's a solid defender and is one of the reasons why Wasps did so well", Jones said.

"We have to put our best foot forward if we want to win the Six Nations", Jones said.

"Jack's been someone we've had on the radar for a long time, since 2018".

"We've told the players they've got to be responsible and they all understand that right at this moment and then there could be a moment when they don't understand it".

"He has a good work attitude about him".

England players were all warned about the risks of breaching their secure environment at the Lensbury Club in London ahead of Saturday's Six Nations finale against Italy.

Jones has defended the omission from his autumn squad of Sam and Joe Simmonds, who have been instrumental to Exeter's rise as double winners. There is no place for his brother, Sam, either.

"Ultimately selection is a judgement situation". It's my judgement call with the coaches.

"I can't sit here and tell you 100% we're going to be ideal".

Meanwhile, Henry Slade, a centre who covers at fly-half, was included fresh from starring in Exeter's 19-13 win over Wasps in the Premiership final at Twickenham last Saturday.

"It was a tough squad to pick and I know there are a number of disappointed players that have just missed out".

Completing the list are Exeter tight five forwards Jonny Hill and Harry Williams and Wasps lock Joe Launchbury and scrum-half Dan Robson. There is also a return for Bath wing Joe Cokanasiga, who last played for the red rose team during the World Cup.

Jones is due to name his matchday 23 for the coronavirus-delayed clash on Thursday, having seen his preparations disrupted by the when England's warm-up fixture against the Barbarians on Sunday was cancelled several of the invitational side's players, including former England captain Chris Robshaw, broke Covid-19 health protocols.

England coach Jones, however, compared the call-off to the time past year when his eventual losing finalists World Cup pool match against France in Japan was scuppered by Typhoon Hagibis.

"I've been around a while so I just accepted it and quickly went up to my room and worked out a Plan B".
