Bath Rugby's Will Stuart, Beno Obano, Anthony Watson and Sam Underhill have been selected in Eddie Jones' 28-man England squad for the 2021 Guinness Six Nations.
Paolo Odogwu and Harry Randall receive their first call-ups to the senior team, both having played for England at U20 level.
Owen Farrell will captain England for the tournament and there is a return from injury for Courtney Lawes.
Elsewhere, Elliot Daly and Anthony Watson could reach their 50-cap milestones during the championship and Beno Obano may be in line to get his first cap.
England will retain a 28-player squad throughout the tournament, following an agreement with Premiership Rugby, The RPA and The RFU in recognition of the challenges presented by COVID-19.
The squad will meet up at St. George’s Park, England football’s training base, on Wednesday 27 January. They will then move to their base, The Lensbury in Teddington, ahead of their first game against Scotland at Twickenham Stadium on Saturday 6 February (kick-off 16:45).
Jones has also named a 12-player shadow squad, who will be part of the same testing protocols as the tournament squad.
Mako Vunipola will join with the squad to undertake rehab during the tournament.
Following their opening match, the Calcutta Cup, England will then host Italy on Saturday 13 February (kick-off 14:15) before playing Wales away on Saturday 27 February (kick-off 16:45).
Jones’ side will return to Twickenham to face France on Saturday 13 March (kick-off 16:45) before travelling to Dublin for their final game, against Ireland, on Saturday 20 March (kick-off 16:45).
England’s home matches, along with Ireland v England, are live on ITV. Wales v England is live on the BBC.
