Newcastle boss Alan Shearer hopes to have three key players available for his first game in charge against Chelsea tomorrow.
Steven Taylor (ankle) and Sebastien Bassong (groin) are improving and have not yet been ruled out, while Damien Duff (hamstring) was expected to train today.
Danny Guthrie is back in contention after an eight-match lay-off with a torn hamstring and strikers Andy Carroll (ankle) and Xisco (fractured toe) have returned to training.
But Shola Ameobi is out with an ankle problem and Joey Barton (fractured metatarsal), Mark Viduka and Ignacio Gonzalez (both Achilles) remain on the sidelines.
Provisional squad: Harper, Forster, Krul, S Taylor, Beye, Bassong, Coloccini, Enrique, Edgar, Cacapa, Butt, Duff, R Taylor, Gutierrez, Nolan, Guthrie, Lovenkrands, Geremi, Smith, Martins, Owen, Carroll, Xisco.
