NFL coaching legend acknowledges rumors of serious health issues

Such awful news.

Former NFL head coach Marty Schottenheimer, now 73, has been diagnosed with Early-onset Alzheimer's, per ESPN.

According to the report, he was diagnosed with the dreadful brain disease that is the sixth-leading cause of death in America.

"He's in the best of health, [but] sometimes he just doesn't remember everything," Schottenheimer's wife said, per ESPN. "He functions extremely well, plays golf several times a week. He's got that memory lag where he'll ask you the same question three or four times.

"He remembers people and faces, and he pulls out strange things that I've never heard, but he's doing well. It's going be a long road. We both know that."

According to the report, Schottenheimer will soon begin a trial with a new drug designed to slow down the effects of Alzheimer's.

Schottenheimer coaches the Cleveland Browns, Kansas City Chiefs, Washington Redskins and San Diego Chargers from 1984-2006.
