Roma have presented Adriano with an ultimatum after he was pictured shopping and taking photos with fans during a break in Rio de Janeiro.
The Brazilian striker was allowed to go back home for a brief period to recover from a broken arm that he suffered against Lazio last month.
He was seen partying and drinking beer after touching down in Rio and it's said that Roma think he isn't taking his rehabilitation seriously.
The latest images have apparently angered Roma's general manager Gian Paolo Montali.
Il Corriere dello Sport understands he has sent Adriano an ultimatum, demanding that he return to Rome on Thursday or put his future at risk.
Adriano has shown little or no concern at Roma's recent problems, which culminated in the resignation of Claudio Ranieri on Sunday.
The 28-year-old intimated that he wasn't happy at Roma before Christmas because of a lack of first team football.
