Ulster caretaker coach Steve Williams has made two changes to the starting line-up to face Edinburgh at Ravenhill tomorrow night.

Following the crucial win over Connacht last Friday a positive result for Ulster against Edinburgh could see the side move further up the Magners League table and help get their season back on track.

Williams has made two changes to the starting team that took a 30-13 victory away from the Sportsground last week.

Scottish international Rob Dewey will line up against his former club Edinburgh as he replaces Paul Steinmetz at inside centre.

"Dewey is a powerful player and has trained well this week," Williams said. "I know that he's looking forward to running out at Ravenhill against his old club."

Former Ulster academy player David Pollock will start in the back row alongside Neil Best and Roger Wilson with Kieron Dawson acting as cover on the bench.

The powerful back rower made his first Heineken Cup appearance less than two weeks ago against Bourgoin and he is looking forward to running out at Ravenhill.

"Ulster fans are very vocal so no matter how many people come along to watch they always make their presence felt," said the 20-year-old Pollock. "It's such a pleasure to play at Ravenhill because it has such a special atmosphere."

Keen to give such a young talent some more game time Williams said: "After coming off the bench the last two games David deserves the start. It's important to freshen things up and to share the workload."

Williams has made a number of changes to his team selections since assuming the position of caretaker coach almost three weeks ago following Mark McCall's resignation.

"The players I choose to start are chosen because the attributes they have are suited to a particular game.

"For future matches the side that we need to send out will be different but at the minute the players selected have qualities that I think are needed for the task ahead."
