Both have made five appearances so far for the Cumbrians and Keith Curle is delighted with the deal.
He said: “You can tell both lads have got ability. They've gone through the ranks at Newcastle and the next step in their progression was league football.
“They've joined a football club in ourselves which has one eye on youth development. That has been shown with recent youth team players who came through and played a lot of league football before moving up the divisions. These lads weren't brought in as projects.
“They were brought in because they added something to the squad we didn't have."
