Duo come in for Warriors
Glasgow have made two changes from their win over Leinster last weekend for Sunday's meeting with Newport Gwent Dragons.
Ed Kalman starts at tighthead prop in place of Moray Low, who is named among the replacements, while Canadian international Chauncey O'Toole, who joined Warriors on a short-term contract this week, is named at blindside flanker in place of Ryan Wilson who drops out of the match day 23.
Utility back Colin Gregor is included on the bench as he prepares to make his return to action following knee surgery at the end of last season.
Glasgow claimed a 22-19 victory over Leinster at Firhill and head coach Sean Lineen has now urged his side to show they can replicate last season's away form of four wins, three losses and two draws ahead of the visit to Rodney Parade.
They will face the Dragons for the third consecutive season in both the Magners League and Heineken Cup, and Lineen said: "This is a huge game.
"We had a good away record last season of four wins and two draws, but we're travelling down to Newport and it's going to be difficult.
"All six home teams won at the weekend so it's going to form in terms of home advantage but it's going to crack at some point and it would be great for us to do it against Newport on Sunday.
"Newport are going to be tough but it's a good one to get after the high against Leinster."
Reflecting on last week's home win, Lineen added: "It was really important to get a win first up at home in front of the crowd. The new guys all did well and the subs were fantastic when they came on. It was great to see the smile on the players' faces after the game.
"But it's a long season and it's my job to make sure we're organised, prepared and motivated for the game ahead."
