ULSTER v GLOUCESTER, Ravenhill, 8pm (live Sky Sports 2)
Team News: Former Ireland out-half David Humphreys will be on the bench for Ulster's Heineken Cup pool opener against Gloucester. The 36-year-old is suffering from an ankle injury and despite coming through a fitness test this morning, he is to have an impact role with the number 10 jersey going to the fully fit Paddy Wallace.
In all, Ulster coach Mark McCall has made four changes to the team that started last week's Magners League defeat to Glasgow for the tussle with the Guinness Premiership leaders.
With a knee injury ruling back rower Stephen Ferris out for four to six weeks, Ulster will start with a new-look back row against Gloucester. Roger Wilson regains the number 8 jersey while Neil Best moves to openside with versatile lock Matt McCullough named as blindside flanker.
Kieron Dawson's leg injury, sustained in the Glasgow game, is not as serious as initially feared and he is named on the bench as back row cover.
In the battle of the second rows, Ryan Caldwell has been named on the bench with Italian World Cup lock Carlo Del Fava starting alongside former Wallaby Justin Harrison, while the front row of Justin Fitzpatrick, Rory Best and Bryan Young remains unchanged.
The one change in the back-line sees Wallace starting at out-half with Humphreys proving the back-up on the bench.
Meanwhile, Tongan winger Lesley Vainikolo will start his first game for Gloucester since the end of September when he returns to the left winger tonight in Belfast.
The giant winger, who scored five tries on his Guinness Premiership debut against Leeds, has recovered from a muscle problem in his neck and will line-up in a back-three alongside James Simpson-Daniel and full-back Iain Balshaw.
There is another change in Dean Ryan's back-line â00 Mike Tindall returns to the centre alongside Anthony Allen following his recovery from a leg injury. The English side's half-back combination of Rory Lawson and Ryan Lamb remains intact, while Olly Morgan moves to the bench.
Ryan's forward pack also remains unchanged from the one that took on Wasps last Sunday, which means Peter Buxton will skipper the side from the second row alongside Alex Brown.
Ulster lock Del Fava's international team-mate Marco Bortolami, who missed the Wasps game with a shoulder injury, returns to the Gloucester 22.

Coach Speak: Mark McCall (Ulster) - "This game has always been the most important fixture in this part of the season, whether we were coming in to the fixture unbeaten in the Magners League or if in the position we are now in. It is a huge, high pressure game and the players have been looking forward to it for a long time.
"Having a full house at Ravenhill will not only affect our team in a positive way but can also affect the visiting side.
"While there is understandably frustration amongst supporters at how we have played this season, the team and squad need everyone at Ravenhill to get fully behind them on Friday night."
Dean Ryan (Gloucester) - "Some of the rugby we played against Wasps (last Sunday) was some of the best we have played for a long time and even though we lost, we are not allowing ourselves to be too disappointed because of the level of our performance in many areas.
"We stacked up physically and were a genuine threat when in possession. We obviously didn't close the game out which was disappointing but we are not going to beat ourselves up about it because of the good things we did.
"We are relishing this contest â00 it is where the club wants to be in the long-term and why we finished top of the Premiership last season. It is up to us now to carry it forward."

- Ulster have not qualified for the Heineken Cup's quarter-finals since they won the competition in 1999. That is eight years since they have made it out of a pool. Gloucester's best Heineken Cup season saw them reach the semi-finals during the 2000/01 campaign
- Ulster's former Ireland out-half David Humphreys is currently third in the Heineken Cup's list of all-time top scorers. He has scored 554 points in 55 matches in the competition for an average of 10 points per game
