However, his manager Rowett believes he will be there when the transfer window shuts.
"I expect him to stay, I hope he stays," Rowett is quoted as saying by Sky Sports News.
"I'm also pragmatic enough to know it's football and anything can happen in the last few days of the window.
"I imagine he would be the type of player who some teams would covet. I'm a realist but I hope he's still here.
"I can only react and answer what's in front of me. The answer is we haven't had an offer which the club feel is financially viable - or I don't think any strong offer yet.
"Jack has never made any real moves to want to leave and he's contracted to us and we're not even a week away from the first game."
