Both Stephan El Shaarawy and Leonardo Spinazzola are expected to recover from injuries in time to face Manchester United on April 29, but Chris Smalling remains in doubt.
The Giallorossi will meet the Red Devils in the Europa League semi-finals after eliminating Ajax.
The first leg is at Old Trafford on April 29, the second leg is at the Stadio Olimpico in Rome on May 6.
According to Calciomercato.com, both Spinazzola and El Shaarawy will return to action for the Old Trafford tie in two weeks.
Spinazzola is dealing with a muscle injury he sustained in the first leg against Ajax last week, but he will soon return to train with the group.
El Shaarawhy missed the last three games with a bicep injury but is expected to return to training with the rest of the team next week.
Chris Smalling will do everything to face his former club, but a return to action only depends on him.
"He has started the work for individual recovery, I think he is close [to returning], but it's up to him and how he feels," Fonseca said before the Ajax clash on Wednesday.
The home of the former Red Devil was robbed last night by three armed men who broke into his house, forcing him to open the safe.
Nicolò Zaniolo won't be available to face Manchester United as he's still recovering from a knee injury, while Gianluca Mancini is suspended for the first leg.
