The Ospreys back row was part of the 35-man squad preparing for the Dove Men Series against Argentina, Samoa, New Zealand and Australia – to be played out on consecutive weekends at the Millennium Stadium beginning on Saturday 10 November – at the infamous Olympic training village in Poland, but has been managing a shoulder problem which pre-dates his arrival.
The decision to send Jones home at this time is based on a preference for the facilities available in Wales to accommodate the necessary investigations and give the player the most optimal management plan for his injury.
Jones remains a full member of the squad and further details of his problem and any repercussions for selection, if at all, will become apparent once the proper investigations have been undertaken.
