Craig Gordon's agent has dismissed reports that Sunderland have submitted an increased bid of £9million for the highly-rated Hearts goalkeeper.
But Gordon trained with his Hearts team-mates on Wednesday morning and the club insisted it was "business as usual".
And the 24-year-old's agent Andy Evans said: "There are absolutely no developments."
When asked if he had been informed of an increased offer from the Stadium of Light, he said: "No, but that's because there isn't one."
