Manu Tuilagi and Ben Youngs are set to return to England's starting XV for Sunday's pivotal Six Nations showdown with Ireland at Twickenham.
The Leicester pair are expected to take over from outside centre Jonathan Joseph and scrum-half Willi Heinz when head coach Eddie Jones names his side late on Friday morning.
Tuilagi missed the win over Scotland at Murrayfield with a minor groin problem which had forced him off early during the opening defeat against France in Paris, while Youngs is poised to be restored to his familiar role as the starting No 9.

That means George Ford and Owen Farrell will continue their 10-12 alliance despite the physical threat posed by Ireland's imposing centres Bundee Aki and Robbie Henshaw.
Jones retained a squad of 27 to prepare for the encounter with the title-chasing Irish visitors, with cover needed due to minor niggles.

Loosehead is an area of English strength, but Jones is already having to make do without his pre-eminent No 1, Mako Vunipola, as Saracens' veteran Lion is back in Tonga for family reasons. Marler would be the man most likely to step up, having already started in Paris. But if there is any doubt about his involvement, Ellis Genge would start after his match- winning exploits in Edinburgh, with Obano on stand-by for a bench role.
