Sean Everitt has named James Lang as his full back to face Benetton as he looks to solve his back three injury crisis.
The Edinburgh head coach decided Lang was the man to go with but he could also have opted for Mark Bennett or Cammy Scott, with the latter starting a game in that position at the beginning of the season.
Edinburgh have made four changes to the team that was beaten by Munster in their last URC fixture and they've gone as strong as possible for a game of this nature that is a must win.
Out go Wes Goosen through injury as well as Mark Bennett, Hamish Watson and Ben Vellacott who all drop to the bench while Jake Henry, Chris Dean, Ali Price and Luke Crosbie come into the starting XV with the last of those making his 100th appearance for the club.
It's the usual front row with Ewan Ashman at hooker and Pierre Schoeman and WP Nel alongside him.
The engine room sees Grant Gilchrist and Sam Skinner combine once more and there is one change in the forwards with Crosbie coming in for Watson on the flanks. Jamie Ritchie and Bill Mata complete the back row.
Into the half backs and Price replaces Vellacott at scrum half to partner Ben Healy. Matt Currie moves from the wing to the centre to combine with Chris Dean while it's a back three of the returning Henry, Lang and Duhan van der Merwe.
There's a 5/3 split on the bench too with front row replacements Dave Cherry, Boan Venter and Javan Sebastian joined by Marshall Sykes and Hamish Watson while the backs are covered by Vellacott, Cammy Scott and Mark Bennett.
Speaking about his decisions, Everitt said: “Luke [Crosbie] reaching 100 appearances for Edinburgh Rugby is a fantastic achievement and it's something he should be incredibly proud of. He's a true Edinburgh man having come through the academy system. It's set to be a special occasion for him, his family, and the entire club.
“Luke embodies everything we want in an Edinburgh Rugby player - hard work, determination, and a real passion for the jersey. He's a leader on and off the field and he's a huge part of what makes this squad tick. We're all incredibly proud of him and we're going to do everything we can to make his 100th a memorable one.
“This is a cup final for us. We know what's at stake and we're treating it with the importance it deserves. It's winner-takes-all for a play-off spot and the boys are focused on delivering a performance that gets us over the line.
“We've shown great character on the road this season and we'll need every ounce of that again tomorrow afternoon in Treviso.”
