Marty Schottenheimer -- who coached in the NFL for 21 seasons -- has been moved to a hospice facility in North Carolina .... 7 years after he was diagnosed with Alzheimers.
The 77-year-old legend -- a member of the K.C. Chiefs Hall of Fame -- was moved to the facility near his former home in Charlotte, N.C. on Saturday.
He's currently listed in stable condition "following complications from his disease," the family announced.
Marty's wife issued a statement saying, "As a family we are surrounding him with love and are soaking up the prayers and support from all those he impacted through his incredible life.
