Cardiff City have rejected a bid from Sheffield Wednesday for their captain Sean Morrison, TEAMtalk understands.
The 26-year-old has been a hugely important figure for The Bluebirds since joining the club in 2014.
He played over 40 games for Cardiff last season and his displays have attracted interest from a number of rivals in the Championship.
TEAMtalk now understands that Wednesday have made their move with an offer of £3million.
It is understood that Cardiff have rejected the offer, but Wednesday are expected to return with an improved offer.
