Andrea Belotti recently started his recovery following a rib fracture suffered in Roma-Milan.
The ex-Torino striker is struggling to breathe, reports Italian journalist Francesco Balzani, and his return remains uncertain.
Mourinho’s hope is to have Belotti back with the team for the last 2-3 games of the season.
Despite the attacker failing to register a single goal in Serie A this season, Mourinho holds Belotti in high regard.
