Sunderland winger Adnan Januzaj has been ruled out for a minimum of six weeks with an ankle injury. The Belgian, on loan from Manchester United, picked up the injury during Sunderland's 3-2 defeat by Crystal Palace on Saturday. A scan on Tuesday confirmed the 21-year-old has suffered ankle ligament damage. Januzaj has scored once for Sunderland in seven appearances and was sent off against Tottenham earlier this month.
