Iain Henderson is in line to play his first game for Ulster this season when they open their European campaign at Bath on Saturday.
Henderson, who is now club captain in the wake of Rory Best's retirement, will be the last of the province's players who were at the World Cup to return to action.
The 27-year-old second-row will be key to Dan McFarland's hopes of getting an all-important away win in the first round of Champions Cup games.
Ulster's hopes will also be bolstered by the expected returns of pile-driving back-rower Marcell Coetzee, who was rested last weekend, and out-half Billy Burns, who has not featured for the last two games.
Will Addison is also fit again after picking up an injury against Zebre at the start of the month, as is Louis Ludik, which gives McFarland more options to choose from in his backline.
"If we play at our best it'll give us a chance in the group and if we don't, it won't. As simple as that," said McFarland of the impending European challenge and the hopes of making the knockout stages for the second year in a row.
Meanwhile, winger Rob Lyttle has signed a three-year contract extension which will keep the 22-year-old at Ulster until 2023.
