Wales lock Alun Wyn Jones will undergo surgery tomorrow on his elbow which will see him in recovery for six to 12 weeks, ruling him out of the rest of the RBS 6 Nations championship.
Jones picked up the injury to his arm around the 36th minute mark of Wales' climactic victory over Scotland at the Millennium Stadium on Saturday, but after being assessed and treated at half time was able to continue and make a full contribution for the remainder of the game.
However, further investigation to the elbow has revealed a chipped bone and ligament damage which means surgical intervention is the best course of action.
"Alun experienced some swelling to the joint the day after the game and was sent for a scan, after receiving those results and after further consultation with surgeons today, it has been concluded that the chipped bone needs to be removed and the ligament to be repaired in order to ensure a stable joint," said Wales physio Mark Davies.
"The necessary period of recovery will be six to twelve weeks ruling him out of the rest of the six nations and allowing him to target an end of season return for the Ospreys."
Jones will not be replaced in the Wales squad meaning head coach Warren Gatland and his team of coaches will now train with a squad of 34 players as they prepare to face France at the Millennium Stadium a week next Friday night (26th February, Kick-off 8pm).
Nearly 40 players were involved in the first Wales Under 18 training session of the season. WRU National Performance Manager Gethin Watts is excited at the potential shown by the group and expects the Regional Under 18 Championship to hone their skills even further.
