GREEN BAY, Wis. (AP) — Ahman Green, a four-time Pro Bowl running back and the Green Bay Packers’ career rushing leader, said he learned last year that he has early onset Parkinson’s disease. “I know unfortunately there’s a day we eventually, where our clock stops ticking,” Green said. “The way I look at it, my clock is going to stop ticking when I want it to stop ticking.” Green’s NFL career began with the Seattle Seahawks, who selected him out of Nebraska in the third round of the 1998 draft. He played for the Packers from 2000-06, spent 2007-08 with the Houston Texans and returned to Green Bay for one last season.
