Lincoln City have signed former Derby and Notts County defender Jason Beardsley, 22, on non-contract terms.
Free agent Beardsley, who left Stafford in November, began as a trainee at Derby and then played 14 times for the Magpies before a spell in the USA.
He will be available for the Imps' FA Trophy tie at Colwyn Bay on Saturday.
Meanwhile Lincoln striker Bradley Barraclough, also 22, has moved to Northern Premier Division side Buxton on loan until 8 January.
Barraclough joined Lincoln in July 2011 and has made 12 appearances in the Blue Square Bet Premier for the Imps, but has not featured since manager David Holdsworth took charge in October.
