Out go Naomi Thomas with a stress fracture of the shin and Hayley Baxter with a fractured scaphoid. Both UWIC players had been earmarked to play against Australia in the opening fixture and their attacking prowess will be sorely missed.
Their replacements are Cath Foale from Saracens and Gemma Allen from Tylorstown Tigers.
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.
