Saracens head coach Steve Diamond has named his team for the Zurich Wild Card final clash against Gloucester at Twickenham on Saturday (kick off 1pm).
A place in next season's Heineken Cup awaits the winners of the game, and Diamond makes two changes to his starting XV from the side that beat Worcester Warriors 28-10 in last week's semi-final.
Glen Jackson comes into the side at fly-half and the only other change sees Raphael Ibanez start at hooker with Matt Cairns named on the replacements bench.
Diamond said: "We know we have a huge job on our hands against Gloucester. Our forward pack came second best when we played them at Kingsholm a few weeks ago so we know the size of the task ahead of us.
"We will have to step up our performance levels on Saturday. The chance to compete in Europe next season is a big prize and one on which we are focussed."
Gloucester will announced their team after the final team run-through late morning on Friday.

Speaking to the local media this week ahead of the Bath Rugby game, Head Coach Laurie Fisher stressed that the fundamental shape of Gloucester's game is in good shape but that the Cherry and Whites have to look after the ball better and make more of their scoring opportunities.
Skipper for the day Willi Heinz faced the cameras after the 13-18 home loss to Newcastle and expressed real frustration at not being able to back up last week's win at Sale, calling it a performance he and his team-mates are not proud of.
Speaking after the game, Charlie Sharples described it as 'the win that has eluded us.' The winger stressed that Gloucester had stayed positive after the first couple of weeks of the Aviva Premiership season and the 26-13 victory over Sale was a result of that focus.
Gloucester Rugby picked up their first win of the new Aviva Premiership season on Friday night, easing to a 26-13 win on the road at Sale Sharks. Director of Rugby David Humphreys was full of praise for his players on the night.
Greig Laidlaw is back to skipper Gloucester Rugby in Saturday's Aviva Premiership derby game against Bath Rugby at Kingsholm. James Hook will make his first start of the season at full-back and Billy Twelvetrees will make his 100th competitive appearance for the club.
Wednesday evening saw the launch of the Cherry and White Wednesday show on the Drivetime programme on BBC Radio Gloucestershire, with Henry Trinder live in the studio to kick off a regular weekly slot.
