Scotland's World Cup quartet return for Edinburgh
Edinburgh will welcome back a quartet of World Cup stars as they look to reignite their Guinness Pro12 campaign.
The Gunners saw their run of five straight victories at the start of the new season halted by back-to-back defeats against Zebre and Connacht.
But their hopes of beating Munster at Murrayfield on Saturday have been boosted by the return of front-rowers Alasdair Dickinson, Ross Ford, WP Nel and centre Matt Scott.
Dickinson, Ford and Nel - who touched down against the United States - played in all five of Scotland's World Cup matches as they reached the quarter-finals.
Scott missed the last-eight clash with Australia with a back injury but scored a bonus-point try in the pool win over the States.
Munster have just lost one game so far this season against table-toppers Scarlets.
Head coach Alan Solomons said: "We are only too aware of the challenge that we face on Saturday and know that we need to be at our best."
Eighteen-year-old Blair Kinghorn keeps his starting spot at full-back with winger Damien Hoyland retaining the 14 shirt.
Will Helu moves from left wing to outside centre with Scott in at inside centre replacing the injured Sam Beard while Tom Brown replaces Helu at 11.
Greig Tonks is now fully recovered and comes in at stand-off to replace the injured Phil Burleigh with scrum-half Sam Hidalgo-Clyne completing the half-back partnership.
In addition to the returning front row, Alex Toolis moves up from the bench to pair Anton Bresler in the second row, replacing the unavailable Fraser McKenzie.
Mike Coman will again lead the team out at blindside, with Hamish Watson returning at openside and Cornell Du Preez moving up from the bench to start in the number eight jersey.
