Gillingham have signed defender Deji Oshilaja on loan until 3 January. The 22 year old has previously been loaned to Newport, Sheff Weds and AFC Wimbledon.
Oshilaja played under Gillingham boss Justin Edinburgh at Newport in 2013-14.
"I know what he is capable of and was keen to get him on board here at Gillingham if it were possible," Edinburgh told the club website.
"We thank Cardiff for allowing him to join us and we look forward to working with him."
He is Gillingham's seventh signing of the summer transfer window.
