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.

Gloucester have been in good form in recent weeks, but Backs Coach Tim Taylor knows that the Cherry and Whites will have to be at their best on Thursday evening (kick off 7:45pm) against a Stade Rochelais side flying high this season.
Speaking to GRTV after the bonus point win over Bristol, back row Lewis Ludlow revealed that despite a tricky first half, Gloucester backed their skills to come through, a faith that was evident in a strong second half showing.
Willi Heinz scored Gloucester's second try as the Cherry and Whites overturned a disappointing first 40 minutes and 0-6 half time deficit, to earn a 26-18 Aviva Premiership victory over Bristol Rugby on Saturday.
It's the first Gloucester-Bristol derby at Kingsholm in over eight years this Saturday (kick off 4:30pm) and, previewing the game with the local media this week, Defence Coach Jonny Bell stressed that, with both teams in the bottom half of the table, they both need the points.
Speaking to the local media this week, Gloucester front rower John Afoa knows the challenge ahead this week against Bristol, and calls on the Cherry and Whites to make the most of home advantage as a determined squad look to bounce back from a narrow loss to Saracens.
Tom Savage speaks to GRTV and the local media as Gloucester went down by 24-20 at Saracens on Sunday afternoon. The second row was disappointed with the result, despite a strong showing from the hosts.
Having named an unchanged starting XV for the past three Aviva Premiership games, Gloucester Rugby ring the changes and retain only five players for Thursday's visit of Stade Rochelais in the European Rugby Challenge Cup (kick off 7:45pm).
