Scarlets are set to receive a significant boost with openside flanker James Davies in line to make his comeback from injury on Sunday.
Davies, who was in fine form for the Welsh region until he suffered a broken bone in his foot in November, could return against Edinburgh.
That of course has delighted head coach Wayne Pivac ahead of the away trip, with his side overcoming Ulster on the road last weekend.
"He's been training really well and we're excited to have him back," he told BBC Sport about Davies' progress.
"He's in a really good place, he'll either start or come off the bench but will be involved in the 23."
Pivac added: "He's been top of the league last year in terms of turnovers at the breakdown."
"Prior to the injury he was leading our team stats in terms of metres carrying the ball and defensive tackles and his all round game was excellent."
Scarlets will also be boosted by the availability of scrum-half Aled Davies after he was on Tuesday released from the Wales training squad.
