FABRICIO Coloccini’s knee injury was today being assessed by Newcastle United.
The defender suffered medial ligament damage in yesterday’s 1-0 defeat to West Bromwich Albion.
And the club’s medical staff fear Coloccini could be sidelined for as many as six weeks.
That would see the 31-year-old miss seven games – including the Tyne-Wear derby against Sunderland on February 1.
The Magpies’ influential captain had a spell out with a groin injury suffered on international duty with Argentina earlier in the season, and manager Alan Pardew must now wait for the injury to be scanned.
“That looks like a four to six week injury,” Pardew said. “We’ll have to wait and see.”
Coloccini limped off shortly after his defensive colleague Mathieu Debuchy was shown a red card, and Saido Berahino claimed all three points for West Brom in the 87th minute with a late penalty after keeper Tim Krul brought down Matej Vydra.
“That (Coloccini’s injury) unsettled us,” said Pardew.
“We had to make changes at the back. I changed it three times. That’s never good news.”
