McCormack's future was the subject of mounting speculation last week with Blackpool reported to be ready to make a £1million bid for the Scot.
But following Leeds' 5-0 friendly win at Farsley, the 26-year-old told reporters: "We've signed a couple of players and I think everyone knows that a few players are going to have to go out to balance the squad and probably balance the books as well.
"At the minute there's a lot of speculation about me, but I don't want to go.
"The manager knows that, my agent knows that so it's all pretty clear. If anything, maybe something could happen with my contract."
Meanwhile, manager Brian McDermott is hoping to complete his fourth summer signing.
He said: "There's one person in particular I'm working on and have been for such a long time. I hope to get some kind of outcome on that.
"Every one of the players I've tried to sign have been important to me and this is another one.
"I'm always optimistic and there's another club involved, but if we can do the deal then we'll do it."
McDermott, who has brought in Matt Smith, Luke Murphy and Noel Hunt this summer, has recently been linked with a move for Peterborough defender/midfielder Tommy Rowe.
Posh director of football Barry Fry confirmed last month that Leeds had enquired about the left-sided 24-year-old.
