Euro 2012 qual. - Balotelli tells coach: I need help
The 20-year-old was excluded from the national side in the wake of his red card in City's Europa League second-leg clash against Dynamo Kiev.
"I spoke to Balotelli," Prandelli said. "He realised that he had made a stupid mistake.
"He told me: 'I need help - I always spoil everything'."
However Prandelli handed both players an olive branch, saying that they could be recalled as soon as the next game.
"The code of ethics applies to one game," he said. "It is quite possible that they can be with us for the match against Ukraine on Tuesday."
Italy play Slovenia in qualifying on March 25 in Hudinja and four days later head continue to Kiev for an international friendly.
