England prop Mako Vunipola will miss Sunday's Six Nations game against Ireland after returning to Tonga for family reasons.
Vunipola, 29, was not selected for England's opening weekend defeat by France, but started in the round two win over Scotland at Murrayfield.
Bath's Beno Obano has been drafted into Eddie Jones' 33-man squad as cover.
Joe Marler is set to return at loose-head prop, with Ellis Genge resuming his role as a replacement.
"If it is going to be a massive set-piece battle, Marler is the best scrummager," England and Harlequins scrum-half Danny Care told the BBC's Rugby Union Weekly podcast.
Meanwhile, Genge made a significant impact in Edinburgh, scoring the decisive try in the 13-6 victory.
"I think Genge is looking angry, and looking physical, and is demanding the ball and is doing some really cute things on the pitch," added former England wing Ugo Monye.
Key centres Manu Tuilagi and Henry Slade are both included in the training squad after recovering from injury.
Tuilagi is on track for a return to the side after a minor groin niggle, but Slade's involvement is in doubt given his two-month absence with a fractured ankle.
