Newcastle United boss Alan Pardew feels Sylvain Marveaux will be out for four months following surgery.
Marveaux is facing four months on the sidelines after undergoing surgery on a groin problem in America.
Pardew said: "Marveaux had a successful operation in America, so we are really pleased about that.
"We think that's going to be three to four months, perhaps four months, but it was a very successful operation."
