West Ham manager Sam Allardyce was left to lament further injuries as midfielders Joe Cole (groin) and Mohamed Diamé (knee) went off in their 3-0 Capital One Cup semi-final second leg defeat to Manchester City.
Allardyce, who handed Andy Carroll his first start of the season, said: "Joe's shouldn't be too long. Mo's looked more serious - and until a scan we don't know - but (the medical department) are saying it may not be as serious as first thought.
"Still I think he would be out for a little while."

West Ham's focus now turns to their fight for Premier League survival, something Allardyce believes hinges on the fitness of his players and new signings.
Ricardo Vaz Te, Guy Demel, Joey O'Brien, George McCartney and Winston Reid are all nearing returns.
"If you give me all them fit from as quickly as possible until the end of the season, I think we'll come out of this," Allardyce said. "Forty (points) is the safe zone over more than 10 years now. It's got to be 22 points minimum for me in the last 16 (games)."
