Diatta made two Premier League appearances for Newcastle in 2008
Doncaster Rovers have completed the signing of defender Lamine Diatta on a two-month contract, subject to international clearance.
The 36-year-old former Senegal captain is a free agent and his last club was Etoile Sportive du Sahel, whom he last played for in July.
He has played for Rennes, Lyon, Besiktas and Newcastle.
Rovers manager Dean Saunders told BBC Radio Sheffield: “He’s an experienced player and played in the World Cup.”
He added: “He’s not playing for anyone so we can get him now because we need all the bodies we can get.”
