Manchester City face an anxious wait to find out the extent of the injury suffered by striker Sergio Aguero in the 5-1 win against Tottenham at White Hart Lane.
Aguero, who had given City the lead when he met a fine Silva through-ball and produced a superb finish past the onrushing Hugo Lloris, limped off before half-time after taking a knock and was replaced by Stevan Jovetic.
Coach Manuel Pellegrini told BT Sport: "We will see tomorrow with the doctor what happened with Sergio. It's possible it was a consequence of him playing 90 minutes [against Watford in the FA Cup at the weekend].
"We hope we can recover him as soon as possible."
Skipper Vincent Kompany added: "It's bad news, of course, but we will have to see. We don't know how bad it is, but hopefully he'll be back very soon."
