Manchester United midfielder Tom Cleverley is expected to be sidelined for four weeks following the foot injury he suffered in Saturday's win at Bolton Wanderers.
Cleverley was forced out of the 5-0 victory at the Reebok Stadium after just five minutes following a challenge by Kevin Davies near the halfway line.
United boss Sir Alex Ferguson initially feared that Cleverley had broken a bone in his foot and was critical of Davies' tackle after the match.
"It is unfortunate but we expected it," said Ferguson after the game. "It was a bad tackle."
However, the Premier League champions have now confirmed that the England hopeful has not broken his foot and has merely suffered ligament damage.
The extent of the injury means Cleverley is likely to be absent for around a month, forcing him out of the start of United's UEFA Champions League campaign.
Cleverley, who was called up to the England squad for the recent Euro 2012 qualifying wins over Bulgaria and Wales, is also a doubt to be available to Fabio Capello for next month's final fixture with Montenegro.
The 22-year-old had enjoyed a positive start to the campaign after breaking into United's starting line-up for the opening Premier League game against West Brom on the back of an impressive substitute's appearance in the Community Shield.
He was replaced against Bolton by Michael Carrick, who is now likely to start when United play Benfica in Portugal on Wednesday in their opening Champions League group fixture.
