England's exciting uncapped duo of Bristol scrumhalf Harry Randall and Wasps wing/centre Paolo Odogwu were eye-catching names among the 28-man Six Nations squad named by coach Eddie Jones.

Yet the most notable omission was that of Bristol prop Kyle Sinckler when Australian Jones, currently in isolation after after assistant coach Matt Proudfoot tested positive for COVID-19, named his squad on Friday.

Randall, who is also qualified to represent Wales, has been in sparkling form during Bristol's bright start to the Premiership season and will vie with Dan Robson to back up regular No.9 Ben Youngs.

Odogwu, who scored two tries in a man-of-the-match performance against Bath two weeks ago, is another now "claimed" for the red rose, having been eligible to play for Italy through his father.

A third uncapped player, Bath prop Ben Obano, has also been included.

Bristol prop Sinckler was suspended for England's opening game against Scotland on February 6 after swearing at the referee in a club game but would have been available for the rest of the tournament.

Jones was non-committal about whether Sinckler would return for the second game, despite not including him in a "shadow squad".

Jones was forced to limit his squad to less than his usual 30-plus names and will have fewer training days because of COVID-19 restrictions related to players moving back and forth between the England camp and their clubs.

As a result, he has also named a shadow squad of 12 that mostly comprises inexperienced or uncapped players, who will follow the England COVID protocols, although Bath pair Jonathan Joseph and Charlie Ewels both feature.

Having spent most of the last four years refusing to pick three halfbacks in his training squads, Jones has now gone for a trio in the smaller group, having found it impossible to ignore the sparky inventiveness of 23-year-old Randall.

"We've been watching Harry for a long time now, at least two seasons," said Jones.

"He'll put pressure on Benny Youngs and Dan Robson, which is a good thing, but it's not so much the youth, it's the quality of his play that's the key thing for us."

Odogwu's versatility earned him a somewhat unexpected call-up.

"He's got power, got a bit of an X-factor. He has the ability to beat people, he's got a good sense for the line," said Jones.

"We're looking for another centre or winger who has that and he's been consistently dynamic in being able to break lines."

England will meet up at the national football team's training base at St George's Park in the Midlands on January 27 to begin their build-up to the opening game of their Six Nations title defence at home to the Scots.
