Bradford City have rejected Sheffield United's approach to speak to boss Phil Parkinson, BBC Radio Sheffield reports.
It is understood there is figure that would trigger a release clause in Parkinson's contract.
The Blades are looking for a new boss after parting company with Nigel Clough on Monday after they lost to Swindon in the League One play-offs.
Parkinson, 47, is under contract at Bradford until the end of next season.
