Former Bulls loanee Micah Evans is the fourth member of last season's squad to join Southport this summer.
Evans joins the Sandgrounders alongside Dom Collins, Daniel Lloyd-Weston, and Richard Brodie after being released by Burnley.
Former Bulls boss Martin Foyle told the club's official site: "Micah has trained well in pre-season. He will offer a great deal in variety of areas for us and I am delighted he has agreed to join us."
Evans, 21, played six times for the Bulls after signing on loan last November.
