Vincent Kompany could miss the next two matches due to the pulled calf muscle he suffered during Manchester City's 1-0 FA Cup fourth-round win at Stoke City on Saturday.
City travel to Queens Park Rangers on Tuesday before hosting Liverpool on Sunday. David Platt, the assistant manager, said: "I think we'll lose Vincent Kompany for a little while. It's too early to say how long he will be out but he has a slight pull on his calf and will miss the midweek game. We will have to assess the injury over the next 24 hours to get a better picture but he won't play against QPR."
Kompany, who limped off after 40 minutes, later tweeted: "On to the next round and a fifth consecutive clean sheet! I hope I won't be out for too long but the team seems to be strong as ever." And: "Tomorrow [Sunday] is the day I start working myself back to full fitness! Hard work will pay off!"
Kompany suffered calf injuries towards the end of last season and also during the club's summer tour – in July, he had to leave early from Malaysia to fly home for treatment.
