Hull have been attempting to close a deal for Austin.
Dyche told the Burnley Express: "There's been no agreement reached.
"The noises are just the same because there's people hovering and clubs interested, but nothing is appropriate for us at this time so he's getting on with pre-season for us.
"There's no reason to think any different until it becomes any different. He's fine, he's in good shape, listening to what we think is appropriate and he's enjoyed himself since coming back for pre-season."
