Rob Herring will return from Ireland duty to captain Ulster in tomorrow's Pro14 clash against Zebre.
Herring, flown out to Japan as an injury replacement for Sean Cronin, is one of six changes to Dan McFarland's side.
Four of the changes come in the backs, where Rob Lyttle returns to join Will Addison and Louis Ludik in the back-three, while Matt Faddes comes in to partner Luke Marshall in the centre.
There are also changes at half-back, with Bill Johnston and David Shanahan paired together for the first time.
Nick Timoney is the other change, coming into the openside flanker berth.
Irish second-row Ian Nagle returns to Michael Bradley's Zebre team for their trip to Belfast.
