Llanelli will have to keep a close eye on Wanderers wing Robin Lock.
For the first of two games against Llanelli in eight days, Glamorgan Wanderers have picked from a near full strength squad.
After the win over Pontypool Jason Pocock returns at full back with Scott Sneddon reverting to his normal position at number 10.
In the pack Ross Johnson starts at hooker and takes the captaincy. There will be a late decision made at Number 8 depending on the fitness of Richard Thomas.
Sam Warburton continues his return to full fitness with another start on the bench after impressing as a sub last week. He is joined amongst the replacements by young scrum half Lloyd Williams who has missed nearly all the season with a shoulder injury.
