Jones is out of contract in the Summer and was offered a new deal prior to Christmas but as of yet nothing has been signed. In effect, the full back is entitled to sign a pre-contract agreement with any club he likes and will walk away for free in the Summer.
Sheff Utd are meant to be interested in the defender but no firm approach appears to have been made. Jones seems to be stalling over contract talks and could be weighing up his options.
