Doncaster have completed the signing of Brazilian defender Dennis Souza after international clearance was granted.
The 30-year-old, who previously enjoyed a spell at South Yorkshire rivals Barnsley, joined Rovers on a short-term deal at the beginning of November.
However, he has been unable to feature because the club have been awaiting approval from the Qatar Football Association as his last club was Al-Sailiya Sports.
Souza will now be available for Saturday's match with high-flying Swansea at the Keepmoat Stadium.
