Wallace is included in the 25-man party after recovering from a hamstring injury.

He said: "I certainly hope to be involved - it is a big match, it's the European Cup and everyone in the squad wants to be part of it."

Ulster will start as underdogs against a Stade team sitting eight points clear top of the French league.

The Paris club have won all seven of their league games while Ulster are bottom of the Magners League, with last Friday's victory over Edinburgh their first in five attempts.

Ulster have beaten Stade on their last four visits to Belfast although coach Matt Williams knows a win this time would be a major shock.

"Stade are presently the best club side in the world and they could beat anyone, including Canterbury Crusaders.

"We have absolutely nothing to lose on Saturday.

"The odds are going to be unbelievably stacked against us, but they do not like leaving France and they certainly do not like coming to Belfast.

"No one has had a crack at them yet and we just have to go out and have a go at them. No side is unbeatable."
