Russell, who is leaving the club in the summer, kicked a late touchline conversion in the club’s last home Semi-Final to win the game and 10,000 Warriors supporters will be hoping for another inspired performance from their fly-half against the reigning Champions.
George Horne will partner Russell at scrum-half with Sam Johnson and Nick Grigg starting in midfield. Johnson returns to the side having missed the final game of the regular season against Edinburgh.
Tommy Seymour was also missing at BT Murrayfield that day and he returns to the starting XV and will play alongside DTH van der Merwe and Stuart Hogg in the back three.
Jonny Gray is also fit to play and starts alongside Tim Swinson in the second-row. Ahead of them Jamie Bhatti, Fraser Brown and Zander Fagerson complete the tight forwards.
Ryan Wilson captains the side from Number 8 as Matt Fagerson and Callum Gibbins start on the flanks.
Peter Horne was another player to miss the game against Edinburgh and he is named on an experienced bench that includes club centurions Rob Harley, Chris Fusaro, Henry Pyrgos and Ruaridh Jackson.
The game is heading for a sell-out and the last few hundred tickets can be purchased from glasgowwarriors.org.
Glasgow Warriors Head Coach Dave Rennie said: “At the start of the season our goal was to be playing finals footy at home in front of our family and friends and we’re excited to be running out in front of a 10,000 strong Scotstoun tomorrow night.
“We’ve prepared well and it’s great to be able to bring back Jonny (Gray), Sam (Johnson) Pete (Horne)and Tommy (Seymour) who were late withdrawals ahead of our last game.”
“Scarlets are a quality side, they’re reigning Champions for a reason and we’re looking forward to the challenge on what is will be a special night for our players and supporters.”
