Jimmie Allen showed face at a Pop Warner youth football game over the weekend with some protection ... carrying a hunting knife on his side while taking in the action.
TMZ obtained photos of the country music star with a huge knife in a sheath hanging from his hip. A witness tells us Jimmie showed up Saturday to a Pop Warner game in Lewes, DE ... which feels random because his kids weren't playing and don't live anywhere near Delaware.
Folks who were there say Jimmie had a friendly conversation with the man he was standing next to on the field .
