Tranmere have signed Hull City duo Calaum Jahraldo-Martin and Will Aimson on loan until 1 January.
Striker Jahraldo-Martin, 21, is a Antigua and Barbuda international who joined from Dulwich Hamlet in 2013 and has made two first-team appearances.
Former Eastleigh centre-back Aimson, 20, spent time on loan in the Conference at Tamworth last season.
"They're two talented young players who will add to competition for places," boss Micky Adams told the club website.
Rovers also confirmed that defender Josh Thompson will be out for up to 12 weeks with a hamstring injury.
