Joe Jackson Suffers Mild Stroke
Michael Jackson's father, 84, fell ill at around 10 p.m. on Wednesday at his home in Las Vegas, a source tells PEOPLE, explaining, "He was sitting down and then found he couldn't stand up. When he finally was able to, he found himself without balance and falling into the walls."
Experiencing "tightness in his head," Jackson then called a friend and told them something didn't feel right, the source says. The friend then came to Joe's house and took him to the hospital.
Jackson, who is being treated at University Medical Center in Las Vegas, will likely be released on Friday. Wife Katherine is with him, and some of his kids are on their way.
"He feels okay," the source says.
Jackson is known for managing the careers of his family of entertainers.
X17 was the first to report Joe's health scare.
