Cross and Lutui to start in Swansea
Edinburgh front-row forwards Geoff Cross and Aleki Lutui will start their first match of the season against Ospreys at the Liberty Stadium on Saturday.
The pair have been promoted from the bench following last week's 16-13 win over Dragons with hooker Ross Ford rested from the squad. Roddy Grant will captain the side in his place.
Head coach Alan Solomons said: "The way things have gone, Geoff and Aleki have had no game time and it's important that they get that as part of a rotation.
"It's now up to them to perform and help maintain the standards set by the pack last week.
"They are experienced international players and should slot in to the side seamlessly, while reselection of the backs allows us to retain a measure of consistency in that area."
Ospreys are playing their first home game of the RaboDirect Pro12 campaign following two victories on the road.
Solomons added: "Ospreys have consistently been one of the top sides in the Pro12. They're always in contention when the competition reaches the business end.
"They're very tough opponents, especially at home, so it's going to be a real challenge for the players. However, the way I look at it, is that it's a wonderful opportunity for them to show what they can do."
