Andy Carroll may have played his last game for West Ham after yet another injury setback.
The former England striker has been missing from the Hammers squad for the last two matches, and manager Manuel Pellegrini has now revealed Carroll has an ankle problem.
Carroll, 30, will be out of contract in the summer and, having started only three Premier League games all season, he is not expected to be offered a new one.
Pellegrini was unable to put a timescale on Carroll's return but his past injury record has raised fears that he will not appear again this term.
"Andy Carroll has an ankle problem," said Pellegrini. "How serious we don't know, I cannot tell you.
"We need to wait for some medical examinations and after that we will know."
Carroll joined West Ham from Liverpool in 2012, initially on loan before agreeing a £15million permanent switch on a six-year contract.
In that time he has started only 84 Premier League matches out of a possible 266 due to a catalogue of injuries.
