Warriors trio Duhan van der Merwe, Rory Sutherland and Renato Giammarioli are all on international duty this weekend.
Van der Merwe starts on the wing, while Sutherland is among the replacements as Scotland get their Test series against Argentina underway this Saturday (kick-off 8.10pm, live on Sky Sports).
Van der Merwe missed the last two games of the Guinness Six Nations through suspension and makes a welcome return to the starting line-up, having scored a try against France at BT Murrayfield in his last outing.
Meanwhile, back-row Giammarioli is on the bench for Italy, who take on Romania at the Arcul de Triumf Stadium in Bucharest (kick-off 8pm, live on Sky Sports).
Capped five times by the Azzurri, Giammarioli put pen to paper on a deal with Warriors this summer ahead of his switch from United Rugby Championship outfit Zebre.
