Southport have signed Carlisle defender Dan Kirkup on a month's loan.
The 19-year-old centre-back signed a one-year professional deal with the Cumbrians in the summer, but has not yet appeared for their first team.
"Playing matches will be fantastic experience for him and it should toughen him up," boss Neil McDonald told his club's website.
"It's a good time for him to join them as Southport are due to play Exeter and Oxford - two ex-Football League teams."
Port have kept just two clean sheets this season.
