Colin, Glasgow Hawks' former Scotland under-21 cap, is needed at full back because of Rory Lamont's leg injury.
Rory damaged a hamstring late in the first half of Glasgows league match against Cardiff at The Arms Parks last Saturday, and was replaced by Colin.
Enlisting the Hawks' full-back is one of four changes Glasgow have made from the team who started against Cardiff. The others are at prop, blind side, and scrum half.
Kevin Tkachuk returns in place of Andrew Kelly at loose head after two weeks with Canada's squad for internationals against Italy and England, and Cammy Mather resumes as blind-side flanker, with Steve Swindall standing down. Steve is thus free to resume with Hawks on Sunday.
Graeme Beveridge starts instead of Sam Pinder, who had been with the Scotland squad earlier this week. Andy Craig, who, like Sam, had been with the national squad, remains at outside centre.
Kenny Logan will captain Glasgow again from the left wing, as he had done against The Borders and Cardiff on the past two weekends this month. His ankle injury at Cardiff has quickly cleared up.
A newcomer appears among the Glasgow replacements. Jonathan van der Schyff, the Currie back-row forward, has been drafted in because of Joe Beardshaw's injury absence.
