Newcastle United midfielder Jack Colback will be sidelined for up to six weeks with a knee injury.

Colback, 26, was replaced in the second half of Sunday's 3-0 Premier League defeat at Sunderland.

Scans have shown the injury is not as serious as initially feared.

Colback, who has started nine of Newcastle's 10 league games this season, will miss at least five matches and will not be available until the middle of December.
