Back rower Beach is on an initial one-month loan from London Welsh and will figure in a much-changed team from the one which featured in the recent British & Irish Cup games with Bedford.
New Zealander Dean Cummins is inked in for his Gnoll debut behind while exciting young winger Dafydd Howells is named in the starting XV for the first time.
Opsreys Academy wing Howells has impressed in the regional age grade and college rugby tournaments and is clearly a name to follow for the future given that he has already featured for the Wales U18 side.
Coach Pat Horgan is also able to welcome back a host of injured players in what is a huge boost for the Welsh All Blacks.
Clashes between Llanelli and Neath are always compelling fixtures and ones which should attract a large festive crowd.
“Depending on a couple of late fitness checks, we could make as many as 10 changes from last week,” said Horgan.
“Some big influences are back and the arrival of Lee Beach and Dean Cummins is a huge boost.
“We are all a little excited about the selection but are very mindful of the challenge Llanelli always pose.
“We must put the two Bedford defeats behind us and pick up quickly where we left off in the League with wins at Swansea and Carmarthen Quins.“
