Helan has joined the League One side on an initial month-long loan deal.
Carlisle United boss Greg Abbott told the club’s official website: “We are starting to build a good relationship with Manchester City and Jeremy is a player who they rate very highly.
“He has a good reputation, he is very versatile, strong and a good footballer, so he will add to the options we already have.
“He’ll join us for training ahead of the trip down to Yeovil and he’s one that we are really looking forward to working with.”
