Bad news for Kim Zolciak ... the Buffalo Bills have 86'd her husband, Kroy Biermann, in their latest round of cuts.
Kroy -- who's played in the league for 8 seasons -- had signed a 1 year deal with Buffalo ... and Kim had already beefed up her cold weather wardrobe to make the trips back East to see him play.
But it wasn't meant to be ... because moments ago, the Bills officially released the 30-year-old linebacker ... and now the big question -- will any other team pick him up?
Biermann has told TMZ Sports he'd be interested in taking up MMA after his NFL career. So, keep an eye out for that.
By the way, Kroy just dropped $100k on a HUGE diamond ring for Kim for their 5 year wedding anniversary.
