Manchester City manager Manuel Pellegrini said that striker Sergio Aguero had been taken off purely as "a precaution" during his side's 3-1 win over Southampton on Saturday.
Aguero recently spent six weeks on the sidelines with a hamstring injury and City's fans feared the worst when the Argentina star was withdrawn in the 64th minute at the Etihad Stadium after appearing to turn his ankle.
But Pellegrini said: "Kun (Aguero) came off as a precaution. I spoke with him before the game and we said he would play 65 minutes. He has a kick in his heel, but nothing important."
City won through goals from Kevin De Bruyne, Fabian Delph and Aleksandar Kolarov, with Shane Long replying for Southampton.
