Former NFL player and general manager Matt Millen says he is being treated for a rare disease that has robbed his heart of most of its normal function.
The 60-year-old Millen told the Morning Call in Allentown, Pennsylvania, he has been diagnosed with amyloidosis, a life-threatening illness that may force Millen to seek a heart transplant. Millen has been receiving chemotherapy once a week to treat a condition that his left his heart functioning at just 30 percent.
Millen played 12 seasons as a linebacker in the NFL for the Raiders, 49ers and Redskins -- and won four Super Bowl rings.
He later served as Detroit's general manager and has also spent three decades as a broadcaster. Millen told the Morning Call that he plans to return to the booth in the fall.
