Morris drops to the bench for tomorrow's game whilst Williams sits out altogether. Luke Treharne takes over in the pivotal role for a game against a Blues side who have enjoyed a particularly rewarding pre season.

Their opening Championship game against the Dragons was postponed last week due to the inclement weather, but team manager Sophie Bennett is hoping the side will continue their run of decent form.

"We did well in the summer and finished off with an excellent victory in Belfast against an Ulster under 19s side. We are all looking forward to getting things underway after the disappointment of last week," said Bennett.

The Ospreys under 16s entertain Blues South at Llandarcy whilst Blues North take on the Dragons at Merthyr.
