Manchester City midfielder Kevin De Bruyne is reportedly due to undergo further scans on a hamstring injury to assess the extent of the damage.
The Belgium international limped off the pitch late in the second half of City's 3-1 victory over Swansea City at the weekend.
Early reports have claimed that De Bruyne is likely to be on the sidelines for one month, missing City's next five games.
There has been no official word from the two-time Premier League champions, but according to Sky Sports News, De Bruyne will have more scans in the coming days.
The midfielder, who has scored two goals so far this season, will miss tomorrow's Champions League group clash against Celtic at Parkhead.
