Coventry hope to welcome back as many as five players.
Defenders James McPake, Richard Wood, Chris Hussey and Martin Cranie all stand a strong chance of being in contention while young midfielder Gael Bigirimana is available once again having completed his three-match suspension.
McPake hobbled off in City's last match before the international break, a 4-2 home defeat to Southampton, but was given the all-clear to return to training while Wood (calf) was withdrawn on the morning on the clash but appears to have recovered.
Full-back Hussey (foot) has missed the last two games while Cranie (ribs) hopes to return after seven weeks out, although a place in manager Andy Thorn's starting XI so soon could be unlikely for the former Portsmouth man.
Coventry do have some injury problems, however, with striker Roy O'Donovan nursing a broken foot while midfielder David Bell will be assessed having sustained a knock in training.
Joey O'Brien and Guy Demel will boost West Ham's injury-hit squad.
O'Brien missed the 2-0 win at Hull a fortnight ago with a hamstring injury but was able to resume training this week.
Fellow full-back Demel is finally pushing to make his debut having been struggling with a hamstring problem since joining from Hamburg in August.
The Ivory Coast international has played in two reserve matches over the past couple of weeks to prove his fitness.
Midfielder Matt Taylor is also close to returning from a calf injury and will be checked over.
But the Hammers are still without defender Winston Reid (shoulder), winger Gary O'Neil (ankle) and on-loan midfield duo Henri Lansbury and David Bentley (both knee).
