The Buffalo Bills improved to 3-0 after defeating the Miami Dolphins 31-21 Thursday night ... but two members of Bills Mafia wanted something more to really make the evening even more memorable -- Ryan Fitzpatrick's chest!!
It all went down during the Prime Video postgame show ... when the folks at Highmark Stadium stuck around to engage with the former Bills quarterback as he was live on air -- with one sign requesting he free the nip.
"That sign is back," he said.
