Former Green Bay Packers star reveals early-onset Parkinson's disease diagnosis

Former Packers running back Ahman Green says he is battling early-onset Parkinson's disease.

Green shared the news on the "Go Long" podcast Wednesday.

"I know unfortunately there's a day we eventually -- where our clock stops ticking," he said. "The way I look at it, my clock is going to stop ticking when I want it to stop ticking."

The former Packers star, 49, played for Green Bay from 2000 to 2006. He also played for the Seattle Seahawks and Houston Texans, returning to the Packers in 2009 for one final NFL season.

Green announced his official football retirement in August 2011.
