Doncaster Rovers manager Dean Saunders has revealed that the club are trying to re-sign former defender Herita Ilunga.
The 30-year-old played 15 times for the club during a loan spell earlier this season before his contract at parent club West Ham United was terminated.
The Congolese international, who recently trained with Leyton Orient, is now wanted back at the Keepmoat Stadium as cover for the injured Tommy Spurr.
"I'm thinking about bringing Ilunga in so he's here," said Saunders. "He's terminated his contract with West Ham and he's been training with Orient just trying to keep himself right.
"We need to do something because if you get injured now you're having to miss four or five games with us playing three a week. We can't afford to go into these games being under-prepared and under-strength. I don't really want to play a right-back and left-back.
"Hopefully we can get him. I'm trying. We'll see how Tommy is. Hopefully Tommy will be okay but, if he's not, we've got someone there who can step in."
Doncaster, who are currently 23rd in the Championship table, host second-placed West Ham on Saturday.
