Duff has gone on record to state he will remain at St James' Park following the Magpies' relegation to the Championship but reports in Ireland have suggested he would be interested in a move to Turf Moor.
The move would certainly make headlines in Lancashire due to the 30-year-old's association with Blackburn, but Duff's advisor Pat Devlin insists there is no chance of it happening.
"No, he's still under contract at Newcastle and that would be his first port of call," he told the Lancashire Telegraph.
"I think someone's winding up the Burnley fans because he's a Blackburn fella."
