By-SA 2.0 4c says:

"You must keep intact all copyright notices for the Work and give the  
Original Author credit reasonable to the medium or means You are  
utilizing by conveying the name (or pseudonym if applicable) of the  
Original Author if supplied"

Note the "if supplied". That would seem to fit this case.
