Ex-NFL linebacker Geno Hayes -- who's only 33 -- is in hospice care in Georgia stemming from liver issues ... and his friends and family are asking for prayers.
"He's fighting for his life," Geno's high school football coach Frankie Carroll told The Tallahassee Democrat.
No word on Geno's specific medical condition or his prognosis -- but clearly, the situation is dire.
He's currently being cared for at his parents' home in Valdosta, Georgia -- where close friends and family members have been visiting in the hopes he can make a recovery.
