The Daily Mirror reports that Blackburn and Wolves have joined Huddersfield, Crystal Palace, Middlesbrough and Bristol City in the chase for the 25-year-old striker.
The Scotland international has snubbed a new deal with Leeds and is expected to leave the club in a deal of around £2.5million this summer.
McCormack scored 19 goals for Leeds United last season.
Leeds boss Neil Warnock confirmed: “There have been enquiries from Ross from a number of clubs who are all keen to sign him.
“I am going to do what is best for Leeds United so, until something happens where I think my club benefits, Ross will continue training with us. And he understands the situation.”
