LONDON, March 7 (Reuters) - Newcastle United centre back Fabricio Coloccini will be out for up to seven weeks after breaking bones in his back, manager Alan Pardew said on Thursday.
The 31-year-old defender has returned to his native Argentina after sustaining the injury when he fell awkwardly during the club's 4-2 Premier League win over Southampton on Feb. 24.
"Colo has gone back to Argentina," Pardew was quoted as saying by local media.
"There's no treatment he can have - he's broken two of the bones in his back. We think it's going to be anything between three and seven weeks. He's gone back for a week."
Coloccini pledged to stay with Newcastle until the end of the season after seeking a move away in January.
He will now miss both legs of Newcastle's Europa League last-16 clash against Anzhi Makhachkala as well as a string of important Premier League matches for the side, who are 15th in the table. (Reporting by Toby Davis; editing by Clare Fallon)
