A source with knowledge of the situation told CNN that Oscar-winning actor Jamie Foxx is still hospitalised in Georgia and under observation.
The person said, "They are running tests and still trying to figure out exactly what happened."
Foxx has been in Atlanta, Georgia, shooting the Netflix film "Back in Action."
Foxx was not taken to the hospital by an emergency vehicle, according to a source who previously told CNN that the medical incident did not occur on the set.
A different insider with knowledge of the movie's production told CNN that filming is "currently underway and expected to wrap up next week."
If Foxx still has scenes to shoot or if he'll be returning to the set, this source didn't go into further detail.
He had a "medical complication," his daughter Corinne Foxx wrote on Instagram on Wednesday evening, adding that her father is "on his way to recovery."
