Mike Maignan completed the whole training session with the team this morning and, according to Gazzetta, he could be available against Atalanta on Sunday and play against Tottenham on March 8.
The France international worked with his teammates for the first time in five months on Wednesday morning at Milanello, while Davide Calabria and Ismael Bennacer continued to train separately.
Alessandro Florenzi also trained with the rest of the group this morning.
Maignan has been forced to the sidelines since September due to a calf injury sustained while on international duty with France. The ex-Lille keeper has missed 22 games across all competitions with Milan, plus the World Cup with Les Blues in Qatar.
According to Gazzetta, Ciprian Tatarusanu is expected to start against Atalanta on Sunday night, but Maignan should play against Fiorentina on March 4 and Tottenham on March 8.
Calabria and Bennacer could also return against the Tuscans next week.
