Rams make signing in time for today's game against Sheffield Wednesday.
Derby County have signed free agent Kalifa Cisse on a non-contract basis.
The 29-year-old central midfielder, who can also perform in defence, has been training with Derby for the last four weeks and has been allocated squad number 34.
International clearance was received late last night and the Mali international will go straight into the Rams’ squad for this afternoon's Sky Bet Championship clash with Sheffield Wednesday at Pride Park Stadium this afternoon.
Head Coach Steve McClaren said: “Kalifa has been training with us for the last few weeks and his fitness has improved during that time.
“We’re a bit short in midfield at the moment, due to injuries and suspensions, and Kalifa is without a club - so it’s an arrangement that works well for both parties.”
Cisse began his career as a trainee in France at Ligue 1 side Toulouse, before moving on to GD Estoril in Portugal in 2004.
It was there that he caught the attention of Portuguese Liga club Boavista, for whom he signed for a year later.
His impressive displays for Boavista led to a move to then Premier League side Reading, as he put pen-to-paper on a three-year deal in May 2007, for a fee of around £1 million.
Cisse made his Premier League debut for Reading against Chelsea in August 2007 and netted his first goal in England four months later, in the Royals’ enthralling 6-4 defeat to Tottenham.
In July 2010, he linked up with Steve Coppell for the second time in his career when he agreed terms on a two-year deal at Bristol City, for another substantial fee.
After 61 league appearances at two goals at Ashton Gate, Cissé signed with the New England Revolution of Major League Soccer in the United States ahead of the 2013 MLS season.
He made six league and two US Open Cup appearances for the Revolution, before leaving the MLS outfit by mutual consent in August, after expressing a desire to return to England.
