The Warriors must win this game and hope that the Border Reivers lose if they are to keep their hopes alive for a Heineken Cup spot next season. Glasgow have however lost their last six matches in the Celtic League picking up just two league points in the process.
Llanelli Scarlets have won three of their last four matches, but away from home the Welshmen have lost their last six games since beating the Dragons 28-16 at Rodney Parade on 23 December. This is the Scarlets first ever visit to Firhill.
The two sides have met on seven previous occasions with Glasgow victorious twice - at Hughenden in November 2004 and at Stradey Park in April 2005.
Referee: TBC. Touch Judges: David Changleng (SRU), Jim Oswald (SRU)
