Ulster scrum half Isaac Boss added: "We have an opportunity to redeem ourselves at Ravenhill next week, it is going to be tough but we have to get back on track and try to start putting the performances in."
Included in the squad is Ballymena clubman Matt McCullough who, if selected this weekend, will gain his 100th cap for his province. Should he take to the field, the 26-year-old McCullough will be one of the youngest players to have reached the landmark 100 appearances for Ulster Rugby and join the elite club which includes names such as Gary Longwell, David Humphreys, Andy Ward and Simon Best.
McCullough won his first Ulster cap against Connacht in 2001 and since then has been a mainstay of the Ulster pack.
Despite being dogged by injury last season, McCullough still managed to make 18 appearances for Ulster and this Friday's encounter against the Ospreys, where Ulster will be out to avenge their 48-17 thumping in Swansea last week, is likely to mark a milestone for the lock-cum-back rower.
