Marouane Fellaini will reportedly miss the rest of Manchester United's festive fixtures with a damaged rib.
United boss Louis van Gaal claimed last week that the Belgian missed the Boxing Day win over Newcastle United with a virus.
However, the Daily Mail claims that the physical midfielder is currently suffering with a rib injury that he picked up in the 3-0 win over Liverpool earlier this month.
As a result, Fellaini will miss the upcoming league games against Tottenham Hotspur and Stoke City, but is expected to return for the FA Cup third-round match against Yeovil Town a week on Sunday.
Fellaini has been a regular as United have won seven of their last eight games in the league.
