Glasgow openside John Barclay has recovered from a stomach bug to make the starting line-up against Ulster in the Magners League at Firhill this Friday.
"Every game is a knock-out game so this Friday is massive for us," said coach Sean Lineen.
"Ulster have won on their last three visits to Firhill and they always get a good following here in Glasgow. But our support has been fantastic all season and I've no doubt that the Glasgow fans will make the most noise and really get behind the players."
The replacements will be announced closer to the game.
GLASGOW (v Ulster): 15 Bernardo Stortoni, 14 Colin Shaw, 13 Max Evans, 12 Graeme Morrison, 11 DTH van der Merwe, 10 Dan Parks, 9 Mark McMillan, 8 Johnnie Beattie, 7 John Barclay, 6 Kelly Brown, 5 Alastair Kellock (capt), 4 Tim Barker, 3 Moray Low, 2 Fergus Thomson, 1 Kevin Tkachuk.
