MacArthur named in Warriors line-up
Sean Lineen has kept personnel changes to a minimum for Glasgow's RaboDirect PRO12 meeting with Connacht at the Sportsground on Saturday.
Pat MacArthur replaces Dougie Hall at hooker in the only change to the starting line-up after Glasgow claimed their fifth straight home win in the competition against Scarlets last week.
Among the replacements will be Duncan Weir, who was an unused substitute for Scotland in their RBS 6 Nations match against Wales.
Head coach Lineen said: "The guys who played against Scarlets have more than earned the right to try to claim us another win on Saturday.
"In terms of the change in the front row, we've got four hookers [MacArthur, Hall, Fergus Thomson and Finlay Gillies] who are all more than capable of filling the jersey, and we want to give them all a window to impress.
"Dougie and Fergus were our two for Scarlets, and now Pat and Finlay have the chance to do the business this weekend.
"Every game is massive for us at this point in the season, and we're confident the players will be inspired by that level of pressure and opportunity."
