L’Equipe state that the 24-year-old, who came off the bench in a 0-0 draw with Romania, suffered a possible fracture to the fifth metatarsal in his hand, but this is yet to be confirmed by the Premier League club.
Nasri is said to have flown straight back to Manchester after the game, where further examinations are to take place to determine the extent of the injury.
The former Arsenal man has started his time at Eastlands well, having an impressive debut in the 5-1 win over Tottenham at White Hart Lane, but it is yet to be seen whether he will be available for City’s Premier League fixture against Wigan on Saturday.
Meanwhile, under-fire chief executive Garry Cook will not watch the game with Wigan at the weekend, as investigations continue surrounding his conduct.
Cook is said to have mistakenly sent an abusive message to Nedum Onuoha’s mother, who is also his agent, belittling her fight against cancer.
Onouha meanwhile has been told that he can train with the first-team squad after failing to secure a move away from Roberto Mancini’s team in the transfer window, and will be considered for the game against the Latics.
