Three Premiership club props, Eric Milligan, Ben Prescott, and Colin Whitaker, have been called in as all four of Glasgow's contracted props, Euan Murray, Andy Kelly, Lee Harrison, and Matt Proudfoot, miss out through injury.
Eric Milligan (Hawks) played as a replacement last week against Edinburgh at Meadowbank, and tomorrow he will play at loose head, starting for the first time. Ben Prescott (Aberdeen GSFP) who has been on Glasgow duty for the past two weeks, has switched to tight head in place of Matt Proudfoot.
Former Scotland under-21 prop, Colin Whitaker (Dundee HSFP), is on the replacements' bench. Mark Sitch, Glasgow Hawks' back-row forward has also been called up. Mark played as a replacement for Glasgow in the Hughenden game against Munster in March.
Jon Petrie and Paul Dearlove drop out because of injury. Roland Reid and Andrew Wilson return as respectively No.8 and blind-side flanker. Dan Parks will skipper Glasgow as he did for the Wrexham match against Llanelli Scarlets two weeks ago.
Glasgow make one other personnel change from the starting line-up in the Edinburgh game as Glenn Metcalfe switches from the right wing to full back in place of Moffat">Stuart Moffat. David Millard returns on the right wing.
Glenn will be playing his last game in a Glasgow jersey so he, his teammates and supporters will be determind to sign off with a victory.
