Fulham have rejected a £10 million bid from Sheffield Wednesday for striker Ross McCormack, Press Association Sport reports.
The Craven Cottage club paid around £11m to sign the Scotland forward from Leeds last summer following their relegation from the Premier League.
However, McCormack has impressed in West London, leading to reported interest from clubs including Norwich and Middlesbrough.
Fulham acted to secure the 29-year-old's future a fortnight ago as he signed a one-year contract extension until the summer of 2019.
