Nigel Melville knows it'll be tough in Ulster, and the Gloucester director of rugby is well aware of how important the Friday night game at Ravenhill is to his side's chances of Heineken Cup quarter-final qualification.
Gloucester currently sit in second place in pool six on 13 points, one point behind leaders Stade Francais, who they place at Kingsholm on Sunday 16 January. The West Country club know that two wins from the next two games would see them top the group, but defeat in Ulster could end their chances.
Commenting on www.gloucesterrugbyclub.com Melville said: "Of course it's going to be hard out there. They've got a superb record at home, just like all of the Irish provinces. It looks like the wind and rain will be in force, but we know that we have to win. We believe that we can qualify for the knock-out stages, but to keep us in control we have to get the points in Ireland."
Melville and coach Dean Ryan recall hooker James Parkes, in place of Mefin Davies, who has played the last three games for Gloucester. Parkes and Academy player Rob Elloway are Gloucester's last two registered hookers, after long term injuries to Chris Fortey and Olivier Azam.
Elsewhere in the line-up Simon Amor returns to the side at stand-off with Henry Paul moving to inside centre. James Bailey replaces Seti Kiole on the left wing, as the Tongan is not registered for European competition.
Absent through injury are Duncan McRae (knee - expected return 16/22 January), Chris Fortey (ankle - long term), Olivier Azam (shoulder - February/March), James Simpson-Daniel (shoulder - mid/end of January), Oliver Morgan (wrist - mid-January), Rory Teague (thumb - end of January), Brad Davies (ankle - week by week) and James Merriman (knee - February).

With such a short turnaround between the two games, and Gloucester looking to reintegrate several players into the line-up after the Autumn international series, Tom Savage told GRTV that the Cherry and Whites will keep changes to a minimum for the European Rugby Challenge Cup game in Zebre on Saturday.
Gloucester travel to Italy this weekend to take on Zebre in Round Four of the European Rugby Challenge Cup. The Cherry and Whites defeated the Italian side 35-10 last Sunday, but Director of Rugby David Humphreys is looking for an improved performance in the return fixture.
Skipper Billy Twelvetrees, speaking to GRTV after the 35-10 over Zebre, was happy with the bonus point win over the Italian side but admitted Gloucester will need to tighten up for the return fixture in Parma.
Gloucester Rugby welcome Sione Kalamafoni, Greig Laidlaw and Tom Palmer back to the starting line up and feature David Halaifonua in a matchday squad for the first time, as they resume Aviva Premiership action against Bath Rugby at Kingsholm on Saturday (kick off 5:30pm).
