A cartilage injury has ruled the 29-year-old flanker out of the Games. Fellow Welsh international back row forward Rhys Oakley has been called into the squad as his replacement. Oakley - like Ringer - plays his rugby for the Newport Gwent Dragons.
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.
