Manchester City caretaker manager Brian Kidd has conceded that he is unsure of the severity of the injury sustained by Kolo Toure on Tuesday night.
The Ivorian limped off after just 15 minutes of the side's 2-0 victory over already-relegated Reading at the Madejski.
However, Kidd believes that the problem is not as big as first thought by the staff.
"At the moment they don't think it's as bad as they first feared, so we'll get a better idea [on Wednesday]," he said.
City host Norwich City in their final match of the season on Sunday.
