Milan defender Mateo Musacchio reportedly closes in on a return to action, after a long spell out with an ankle injury.
The 30-year-old, who struggled to accept that the Rossoneri replaced him in the starting line-up with Simon Kjaer in January, has been out with an ankle injury since mid-June.
Musacchio required surgery during the summer, but Il Corriere dello Sport claims the Argentine is on the right path and should soon recover from the setback.
The good news adds to the return of Leo Duarte, who tested negative for coronavirus after a long quarantine period.
Matteo Gabbia is still positive for COVID-19 ahead of the match against Celtic, but captain Alessio Romagnoli has returned to partner Kjaer in defence.
