Gavin Henson will make his Cardiff Blues debut playing at full-back for Friday's Pro12 Welsh derby against the Dragons at the Cardiff City Stadium.
The home team shows four changes, all in the backs, to the team that lost to Edinburgh last Friday.
New recruit Henson will make his debut at full back, with Leigh Halfpenny moving to the wing.
Alex Cuthbert returns to the other wing, having recovered from a hamstring injury. In the centre Dafydd Hewitt starts with Jamie Roberts moving to the bench and Ceri Sweeney starts at fly half with Dan Parks also moving to the bench. The pack remains unchanged.
Henson is hoping to impress the Blues coaches and secure a long-term deal with the region.
"I'm incredibly grateful to the Blues for giving me a chance, it's kind of like a trial thing until the end of the season," Henson told BBC Wales.
"So I'll be going all-out all season now to try and get another contract with them.
"Everyone knows I've been a little bit injury-prone over the last four or five years, so I'm not much of a signing to anyone - so very grateful the Blues gave me a chance. It's up to me now to repay that and just try and get that long-term contract with them.
"I'm just glad to be starting; obviously not my preferred position, but nevermind. I'm just glad to be on the field and it'll be interesting to see how it goes," he added.
"I've been training hard so hopefully I'm up to the standard and it could be an exciting night.
"With Leigh [Halfpenny] and Alex [Cuthbert] there they've been playing really well, so I'm going to enjoy playing alongside them and hopefully they'll help me out quite a bit because it's my first game for a while. It's an exciting backline and very hard to get into, but hopefully we'll have a good result now Friday.
"There's loads of experience throughout the team, but especially the backline. Hopefully it'll be a good turn-out, it's my first time playing in the Cardiff City Stadium so can't wait for that and hopefully it'll be a nice Christmas."
Meanwhile, Dragons centre Lewis Robling will be making his second regional start.
