Wales full back Lee Byrne has lost his battle to help the Ospreys face Munster in the Heineken Cup quarter-finals this weekend.
Byrne failed a fitness test in the Welsh region's final training session today and has been ruled out of Sunday's sell-out clash in Limerick.
Byrne damaged ligaments in his left foot during the Six Nations clash between Wales and Ireland and has not played since. He hopes to be available to play again within a few weeks.
Also missing from the Ospreys line-up is another of their British & Irish Lions contenders, Gavin Henson. He is now two weeks into his recuperation after twisting his ankle in the EDF Energy Cup semi-final defeat to Gloucester.
That caused damage to his ligaments on both the lateral and medial sides of his right ankle and he is likely to be
sidelined for at least another month.
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.
