The actor's daughter, Corinne, shared the health news via Instagram.
"We wanted to share that, my father, Jamie Foxx, experienced a medical complication yesterday," Corinne began the message, written on behalf of the Foxx family. "Luckily, due to quick action and great care, his is already on his way to recovery."
The 29-year-old actress continued, "We know how beloved he is and appreciate your prayers. The family asks for your privacy at this time. Much love, The Foxx Family."
Corinne turned off the comments on the post, and did not go into detail on what the "medical complication" the 55-year-old actor suffered was. ET has reached out to Foxx's rep for comment.
One day before his medical complication, Foxx was photographed on set in Atlanta, Georgia, for his upcoming film, Back in Action. In the shot, Foxx wore a black shirt and matching pants, which he paired with a maroon jacket and a whistle around his neck.
The following day, the crew was notified that Foxx would be two hours late to set because he was ill. Shortly thereafter, however, they got the call that Foxx would not be coming in. Filming was completely suspended on Wednesday in the wake of Foxx's medical complication.
Foxx is starring in the Netflix action comedy, which is being directed by Seth Gordon, alongside Cameron Diaz, Kyle Chandler and Glenn Close. When ET spoke to Foxx last summer, he opened up about how he got Diaz to come out of retirement for the film.
"[I asked her,] 'Do you wanna have some fun? Just have some fun!' And I think that's what brought her to it," he said. "Cameron is such an incredible force and she has done so much in this business. We love her."
