West Ham and former Manchester United goalkeeper Roy Carroll is in a rehabilitation centre receiving treatment for alcohol and gambling addictions.
West Ham have drafted in Gabor Kiraly as cover and manager Alan Pardew has offered his support to the Northern Ireland international.
"We are aware that Roy has problems and we are fully supporting him in any way we can," Pardew told British media.
"He has gone about tackling the issues in the right way and is seeking expert help to sort him out. I understand he will leave the clinic on Wednesday and will be back training with us on Thursday."
