In addition to Christian Pulisic, who has fully recovered from the intestinal issue that prevented him from being at 100% during the big match at San Siro against Napoli on Tuesday, Paulo Fonseca will also have Davide Calabria available again, as relayed via Milan News.

La Gazzetta dello Sport reported today that the 27-year-old Italian right-back could reclaim not only the right flank but also the captain’s armband for Saturday night’s game against Monza at the U-Power stadium.
After several designated captains in recent Milan lineups, Calabria will return to wear the armband again
This month, the armband has alternated between Theo, Leao, and finally Mike Maignan.
This likely means a bench role for Emerson Royal, who has started nearly every game since the match against Venezia, except for the Champions League debut against Liverpool, where he came on as a substitute.
