The Argentine was axed by Dundee in November after the club went into administration.
The 26-year-old is now trying his luck with The Rams, who are looking to bolster their strike-force.
"We were asked if we would take a look at the boy and so he's been with us for a few days and will train again today," said Rams manager George Burley.
Derby are considering bids from Eastern Europe for Pablo Mills and Izale McLeod - and Caballero could be brought in to replace the latter.
