But McLaughlin will be without Stephen Ferris, who picked up a shoulder injury in Galway against Connacht last time out, and BJ Botha who collected a wrist injury in the same game.
It is unclear just how long the pair will be missing but Ulster are boosted with Scotland winger Simon Danielli being included for the first time this season after missing the first few weeks due to a shoulder injury.
With props Botha, Declan Fitzpatrick and Adam Macklin all unavailable because of injury, Instonians' Alan Whitten, a brother of Ulster centre Ian Whitten, is included in the squad.
The other props in the 30-man squad are Tom Court, Paddy McAllister and Brian Young.
