"It's nice to be able to welcome back those who have been on international duty and they will provide us with different options for this week's game," Glasgow boss Gregor Townsend told the club's official website.
"With those internationals back it makes selecting a starting XV that much harder as the squad has been performing at a very high level. Each player knows that they cannot take their place for granted as the quality of the squad is improving all the time.
"They are driving each other to higher levels and that is fantastic for the coaches to see in training and what that can mean when they take to the pitch."
Glasgow currently sit second in the RaboDirect PRO12.
