Named for the first time in a Warriors squad, is summer signing DTH van der Merwe who joined straight from his impressive outings for Canada as he helped guide them to a place in the 2011 Rugby World Cup finals.
Having been ruled out of action since his arrival in Glasgow, Lineen is excited about the prospect of seeing van der Merwe donning a Warriors jersey for the first time.
Lineen continued: "DTH had some bad luck with a dead leg and the flu but he has been looking really sharp and I'm excited about seeing him in action soon after looking pretty impressive over the summer with Canada."
