TMZ previously reported that Kevin underwent major back surgery on Sept. 1. Now the outlet has revealed that during the operation, surgeons repaired three spinal fractures.
Sources told TMZ that doctors fused two breaks in the thoracic region (the mid to upper back) and one in the lumbar region (lower back).
Sources added that Kevin is in a lot of pain and is being heavily medicated to help him cope.
TMZ further reports that though doctors believe Kevin will recover, it will take a lot of work to get there. On Sept. 4, the site reported that the movie star -- who's expected to be released from the hospital later in the week -- will soon begin grueling physical therapy.
