Josh Hartnett is doing well following his hospitalization earlier this week for gastrointestinal problems.
And, in a statement to Access Hollywood, his rep said doctors had yet to diagnose the star.
"Josh Hartnett was released from the hospital earlier this week after being admitted to Cedars-Sinai with gastrointestinal discomfort," his rep said in a statement to Access. "He has undergone a battery of tests to determine the cause and in the meantime he is resting and feeling fine and thanks everyone for their concern."
Hartnett was rushed to the emergency room early Monday.
"Josh Hartnett walked into an ambulance at approximately 1:45 AM [Monday] morning suffering from a flare-up of a gastro-intestinal problem that plagued him while he was starring in the west end of London during the production of 'Rain Man,'" Hartnett's rep previously said in a statement released to Access.
