Sebastien Haller, Felipe Anderson and Mark Noble have all won their race to be fit for West Ham's trip to Watford in the Premier League this weekend.
All three missed the draw at Brighton last time out and in the case of skipper Noble, has yet to feature this season after picking up a calf injury in pre-season.
But all three have trained fully this week with the squad and are fit to be included by the manager if he wants to for the trip to Vicarage Road.
Pellegrini confirmed that they were all ready to go at his pre-match press conference when he revealed that only Winston Reid is the currently injured player in the squad.
"The only injury we have is Winston Reid. All the other players are fit," the manager said at Rush Green.
Haller picked up a swollen knee in the defeat to Man City in opening weekend, while Anderson was forced off in the same game with a thigh injury.
Only Kiwi defender Reid is definitely ruled out as he is still recovering from a 15-month spell on the sidelines after undergoing two knee surgeries in the space of a year.
