The manager has revealed that the unsettled Congolese defender is expected to join in with full training this week after getting the all clear on an MRI scan on his hamstring
The defender has not played for the club since his failed attempt to force through a move away from Ewood Park towards the end of the January transfer window.
But the player is expected to be available for selection again as manager Steve Kean has confirmed that he will join in with training this week.
"He has had a clear scan - he had an MRI scan on his hamstring - which is good news," Kean told reporters.
"I'm sure he will be back in full training early next week."
Kean also revealed that the club did not receive any offers from QPR for top scorer Yakubu in January, despite the striker claiming to have turned down a move to Loftus Road.
"We had no bid from QPR for Yakubu, but I think there was always going to be plenty of interest - it wasn't only from QPR, there were many clubs that showed an interest," he added.
"But when we said he was not for sale, it never got to the stage that there was any bid."
