The Scotland international is being strongly linked with a move away from the Stadium of Light this month.
Fletcher has three goals to his name this term, but has been dogged by injuries which have limited him to 11 starts.
Now a host of Sunderland's Premier League rivals are said to be taking an interest and reports had suggested that Hull City had seen an offer in the region of £8million rejected.
However, sources have confirmed to us that no bid has been made for Fletcher.
We understand that West Bromwich Albion striker Shane Long, who Hull tried to sign on deadline day in September, remains Steve Bruce's top target.
