Inter Milan striker Samuel Eto'o is a doubt for Tuesday's Champions League visit of Dynamo Kiev despite being included in the squad, coach Jose Mourinho said.
Midfielder Esteban Cambiasso is also carrying a knock.
"Today they couldn't train with the group but we'll be able to tell if they can play tomorrow or not. Samuel will at least be in the squad," coach Mourinho told reporters on Monday.
Balotelli played up front on his own at Genoa where the absence of fellow striker Diego Milito was also forgotten thanks to Inter's powerful display.
Argentina's Milito has been missing for three weeks with a hamstring injury but Mourinho said there was an outside chance he could feature, although midfielder Thiago Motta is out.
Inter have two points from their opening two group games having drawn with Barcelona and Rubin Kazan.
"It won't be a decisive game against Kiev. There are still four games and 12 points to finish the group," Mourinho added.
"The best way to prepare for Kiev was to have a moment of joy (at Genoa)."
