A person familiar with the situation told that Oscar-winning actor Jamie Foxx is still in the hospital in Georgia and is being watched.
"They are still running tests and trying to figure out exactly what happened," the person said.
Foxx has been in Atlanta, Georgia, making the Netflix movie "Back in Action."
The person had told CNN before that the medical problem did not happen on the set and that Foxx was not taken to the hospital in an ambulance.
CNN heard from a different source close to the film's making that shooting is "currently going on and should be done next week."
His daughter Corinne Foxx wrote on Instagram on Wednesday night that her father had a "medical complication," but that he is "on his way to recovery."
