Manchester United manager Alex Ferguson says that he suspects Tom Cleverley has a broken foot.
The midfielder was taken off during United's 5-0 win at Bolton on Saturday after a tackle from Kevin Davies.
Cleverley later emerged from the away changing rooms with his foot in a protective cast.
"We think it is a broken foot," said Ferguson. "It is unfortunate but we expected it. It was a bad tackle."
The win took the Red Devils top of the Premier League on goal difference ahead of local rivals Manchester City.
