The Cleveland Browns just cut 26-year-old safety Jermaine Whitehead -- after the guy threatened to shoot, kill and fight several fans on social media after the Browns lost on Sunday.
Whitehead was getting clowned on social media for his lack of tackling and the overall terribleness of the Browns, when he lashed back on Twitter,
"Imma kill you bitch ... that's on blood," he told one guy.
"Don't get shot at lil bitch ... can you whoop my ass .. .f*ck football .. let me know when you need the address," he told another.
