West Ham trio Aaron Cresswell, Havard Nordtveit and Jonathan Calleri have all resumed full training.
Left-back Cresswell is in contention to make his first appearance of the season when the Hammers visit Crystal Palace on Saturday, almost three months after damaging knee ligaments in a friendly with Karlsruher.
Club doctor Stijn Vandenbroucke said midfielder Nordtveit had undergone “a small medical procedure” during the international break, while striker Calleri has not featured since the League Cup win over Accrington three weeks ago.
Arthur Masuaku, who suffered a knee injury in that game, remains in a brace, while Sam Byram underwent surgery on Saturday following his hamstring injury against Middlesbrough earlier this month.
Gokhan Tore is set to be out for four to six weeks with the injury he picked up while on international duty this week.
Attackers Andre Ayew, Diafra Sakho and Andy Carroll are all working intensively on their fitness but are a little way off returning.
