Wales Grand Slam star Rhys Priestland will return to action tomorrow to hand the Scarlets a major boost ahead of their Amlin Challenge Cup quarter-final with Brive.
Priestland struggled with knee problems throughout the Six Nations and missed last weekend's derby victory over Heineken Cup quarter-final hopefuls Cardiff Blues.
But Priestland has been named in the Scarlets starting side to face Edinburgh at Murrayfield, alongside fellow Grand Slam heroes George North and Jon Davies.
"All of the Wales internationals are now available," said Scarlets head coach Nigel Davies.
"We integrated some of them into the game last weekend. Rhys wasn't available, that was the advice medically.
"It is about understanding that there has been a group of players here working to our systems.
"Sports physiology also suggests if you overplay players they lose form and are more likely to get injured. With a big run-in to the season it is about how you manage your squad."
The Scarlets also welcome back Stephen Jones, after the veteran fly-half withdrew from the victory over the Blues with sickness. But Ben Morgan has been left out of the squad after struggling with a hamstring strain.
Following three consecutive bonus-point wins in the league, Davies hopes his side are peaking at the right time.
They face 1998 Heineken Cup winners Brive on April 8, and are also in the play-off hunt in the PRO12.
"We have not been 100 per cent comfortable with our performances, but you can't argue when you pick up bonus point wins," added Davies.
"We are doing some good stuff without the ball, but we need to ally that with being a bit more clinical with the ball. There is a lot more in us."
