Costelow returns as Scarlets change nine for Black Lion
European Challenge Cup: Scarlets v Black Lion
Venue: Parc y Scarlets, Llanelli Date: Sunday, 15 December Kick off: 13:00 GMT
Coverage: Live audio and text commentary on the BBC Sport website and app.
Sam Costelow and Gareth Davies will resume their half-back pairing as Scarlets host Black Lion in the European Challenge Cup on Sunday.
Fly-half Costelow returns for the first time since starting for Wales against South Africa, replacing Ioan Lloyd.
Davies missed the opening weekend of the competition with a minor hip issue, but returns as one of nine changes from the narrow loss at Bayonne, along with centre Johnny Williams.
Wales prop Henry Thomas comes in at tight-head for Sam Wainwright who is to undergo surgery on an ankle injury suffered in the south of France.
Hooker Marnus van der Merwe also returns in the front row after a hamstring issue.
Max Douglas and Sam Lousi form an all-changed second row, while flanker Taine Plumtree returns in the back row along with fellow Wales international Josh Macleod, who reclaims the skipper's armband from Alex Craig.
The two sides meet exactly 12 months to the day since Black Lion stunned Scarlets with a shock 23-7 win in Llanelli in last year's competition.
The Georgians opened this year's campaign by defeating a Top 14 side for the first time, earning a 22-19 win against a depleted RC Vannes in Tbilisi last weekend.
Scarlets assistant coach Emyr Phillips said: "Black Lion showed last year they are a good, well-coached team with that Georgia coaching group in there and have serious players and power as well.
"We realise that home wins are important and they have already picked up a home win so their confidence will be high. But we are in a good place, the squad is excited, the boys have trained well and are looking forward to a European game at home.
"It is a Sunday afternoon kick-off so hopefully we can get a good crowd down here and build on the positives we have had over the last few weeks."
