The club have confirmed that the Frenchman could even be fit for their clash with Hull on Saturday.
“When Lassana left Upton Park on crutches we thought he had a very bad ankle injury. But the injury isn’t as bad as we originally thought,” said Pompey physio Gary Sadler.
“We’ve had a call from him from France. He’s had a scan after reporting to the French medical team.
“The good news is that he could be available for AC Milan. Even better news is that he might even be available for this weekend.
“He’ll return to us on Thursday and we’ll see how he is. He seemed in quite high spirits about things when we spoke to him.”
