(Reuters) - Manchester United's injury-prone defender Phil Jones could be sidelined for around a month due to a knee problem, the Premier League club said in a statement.
The 24-year-old, who is yet to feature for United this season, did not travel with the squad to Rotterdam for Thursday's Europa League fixture against Feyenoord after suffering a knee ligament problem, manager Jose Mourinho said.
