The English club has proposed a new deal that would tie Mokoena to the club until 2011, but he has yet to sign.
The utility player, used mostly in midfield by Blackburn but as a central defender in the national side, is uncertain over whether he will be able to command more regular playing time now that Paul Ince has replaced Mark Hughes.
The previous manager, recently appointed to take charge at Manchester City, used the Bafana skipper mostly as a substitute, the source of much frustration for Mokoena.
Sources confirm there is interest in Mokoena from at least one other English Premiership side as well as one of the top Scottish teams. But no firm offers have been tabled to Blackburn.
Any prospective club would have to pay a transfer fee to Blackburn for the South Africa captain, whose current contract expires only in mid-2009.
