Newcastle skipper Fabricio Coloccini is out of Saturday's Barclays Premier League clash with Liverpool.
The 31-year-old defender returned from international duty with Argentina with a groin problem, but having been assessed by the club's medics, he will play no part against the Reds.
Asked how the international break had served the club, manager Alan Pardew said: "We have had an injury to Colo in that time, so he won't feature this weekend.
"How long he misses, we will have to wait and see, so that was disappointing.
"He has a groin injury, so we will have to see how it repairs itself over the next few days."
