Manchester United midfielder Shinji Kagawa is facing three to four weeks on the sidelines because of a knee injury. United boss Sir Alex Ferguson confirmed the news at his press conference this morning.

"Kagawa is out for three to four weeks with a knee injury. Playing on Tuesday (against Braga in the UEFA Champions League) didn't help. It is disappointing," the Scot said.

On a positive note, Ferguson reported that defender Chris Smalling was back in training following a broken metatarsal. "That is a big bonus for us," Ferguson added. "Phil Jones should start (training) a week on Monday as well." Jones suffered a knee injury in training last month.
