The striker has returned to parent club Watford, although the Cumbrians want to make Garner a permanent signing in the January transfer window
However, on Saturday, Danny Cadamarteri and teenager Mark Beck will be vying for a recall to the starting line-up alongside Lee Miller.
Miller only returned from a five-month injury lay-off due to hernia and ankle injuries in last week's 2-1 defeat at Shrewsbury and manager Greg Abbott is hoping he is OK to continue.
Defender Valentin Gjokaj has been recalled by parent club Derby and Peter Murphy is still recovering from a hernia operation, so Mike Edwards and Danny Livesey are expected to continue at the heart of defence.
Midfielder James Berrett is making steady progress following a groin problem, which has kept him sidelined for the last three matches and striker Rory Loy (broken leg) is not yet ready as the Cumbrians look to bounce back from three straight league defeats.
