Jones is a first year scholar and is due to graduate in the summer of 2020 along with a number of others, including Elechi, Spasov and Lopes. These three however have already been given pro deals up to the summer of 2021, although will technically be able to continue in the U18s, albeit also in the U23s/out on loan.
Pro deals can only be signed once a player reaches his 17th birthday, which this crop will have been doing during this season (if I remember correctly age groups are done on a year by year basis, just like schools, though sounds like the dates run from July-June to match the footie season rather than the school Sept-Aug setup.
Therefore pretty certain that Jones COULD be offered a deal before then, as long as he has reached his 17th birthday, which right now I cant be bothered to look up
