Hall of Fame running back Marshall Faulk has been diagnosed with Parkinson's disease, according to ESPN and CBS Sports.

Faulk, 53, is now the head coach at Southern University, the outlets reported. He talked about his diagnosis on the podcast "The Caring Neurologist," ESPN and CBS Sports said. ESPN said the episode came out Wednesday.

Faulk said he has been living with the disease for about a year and a half, ESPN and CBS Sports reported. He first noticed stiffness in his hands while playing golf, the outlets said. He brought it up at a routine checkup, and the doctor said he needed to get checked, CBS Sports reported.

With medicine, he has had no problems beyond stiff hands and "little tremors," ESPN reported. He said the stiffness has not gotten worse, ESPN and CBS Sports said. He also said he has had no decline in his thinking, ESPN reported.

"I think I caught it early. I'm in a good place," Faulk said, according to CBS Sports.

Faulk said he does not see it as a fatal illness, ESPN reported. He compared it to the knee and back injuries he lives with from football. "It's something you live with," he said, according to ESPN.

"I want to help as many people as I can," Faulk said of speaking out, ESPN reported.

Faulk had not talked about the diagnosis with his family or friends, CBS Sports reported. He said he would if his life changes.

Faulk played for the Indianapolis Colts and the St. Louis Rams, ESPN and CBS Sports reported. He won a Super Bowl with the Rams and was named the league's MVP. He joined the Hall of Fame in 2011, CBS Sports said.

He was an assistant at Colorado under Deion Sanders before Southern hired him, the outlets reported. ESPN said Southern is 3-4 this season.
