Blackburn Rovers and Middlesbrough are rivaling Rangers for Hibs fullback Steven Whittaker.
The 23-year-old's agent, Ken Anderson, told BBC Sport that a deal for the sale of the versatile player could be completed within the next few days.
A fee of between £1.5m and £1.8m will be required to seal the signature of the much-admired former Scotland Under-21 international.
Anderson will hold further talks with the interested clubs on Tuesday.
