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.

Dan Murphy was part of a Gloucester pack which took a grip as the Sale game progressed and, ultimately, were rewarded with a late penalty try. The loose head prop says the team's improved scrummaging is down to a lot of hard work over the summer.
