The Scorpions have enjoyed a mixed martial arts training session as part of their preparation for the Cougars clash.
Captain Aled James said: “There was a lot of wrestling and a lot of grappling. It’s a new technique for us which was good to try out.
“I think the boys came out of it a lot better because they had to buy in to it, compete and basically be honest with each other. It rounded off a good week of training for us.”
“Their arrival really does add some competition for places and it gives people a bit of a push.”
Scott Law remains doubtful with ligament damage, while Jermaine Wray is unavailable due to personal reasons.
Demetriou said: “South Wales are doing quite well, and they’re a dangerous team in attack.
“I like the style of play they’ve got, and we’re expecting a tough challenge. We need to aim up for this one.”
