Samba lost 10lbs in two days after contracting swine flu. The Congo international was struck by the bug after Rovers' 3-2 win over Burnley 11 days ago and has not played since.
Samba, 25, said: "It started like normal flu - a sore throat and a bad cold - but it sapped me of all my energy.
"In two days I lost five kilos. After that you need a few days to recover and regain your rhythm."
