Kevin-Prince Boateng is winning his battle to be fit in time for Sunday's Juventus-Milan clash.
The Ghanaian has been struggling with muscular problems for several weeks, but took part in the full training session today and the game between ranks.
Coach Massimiliano Allegri had also suggested there was “a good chance” of seeing Boateng face Juve this weekend.
It would be a huge boost for the Rossoneri, who have been dealing with an injury crisis all month.
Gennaro Gattuso, Robinho, Massimo Ambrosini, Alexandre Pato, Philippe Mexes, Mathieu Flamini and teenage striker Kingsley Boateng are not expected to recover in time.
Zlatan Ibrahimovic and Luca Antonini made their comebacks in last night's 2-0 win over Viktoria Plzen, while Daniele Bonera is also ready to play.
There are concerns over Ignazio Abate, who had a slight muscular problem during that Champions League tie.
