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. Green rushed for at least 1,163 yards each season from 2000-04 while playing for the Packers. He spent two seasons with Seattle before getting traded to Green Bay in April 2000. He played for the Packers from 2000-06, spent 2007-08 with the Houston Texans and returned to Green Bay for one last season.
