Newcastle could be without goalkeeper Tim Krul for their next five games after he picked up an ankle injury.
The Netherlands international suffered ligament damage during training in the build-up to Saturday's match against West Ham, which Newcastle lost 1-0.
"Rob Elliot will be in goal for the next four or five games," Newcastle manager Alan Pardew said.
Pardew added he was "worried" about defender Daryl Janmaat who came off with an hamstring injury in the game.
Newcastle are already without forward Siem de Jong, midfielders Ryan Taylor, Rolando Aarons and Mehdi Abeid and defenders Fabricio Coloccini and Davide Santon.
"It's been blow after blow this year, but we've rode them and that's been the key to our success," added Pardew, whose side are eighth in the Premier League table with 19 points from 13 games.
"We've put younger players in and those in the group. We lose Tim but Rob's produced a super performance."
