Ireland winger, Andrew Trimble, has recovered from injury and is included in the Ulster team to face Ospreys at the Liberty Stadium tomorrow night, kick off 19:05pm.
Trimble underwent surgery on his finger three weeks ago and starts on the right wing in place of Tommy Bowe, who has failed to recover from a dead leg he sustained in the bonus-point win over Treviso at Ravenhill last Friday.
Ulster Head Coach, Mark Anscombe, has made four changes in total.
Captain Johann Muller returns, while Declan Fitzpatrick is selected at tighthead having recovered from the injury that he picked up against Connacht in Galway.
In the only other change, Nick Williams, who signed a new two-year deal with the province this week, starts at Number 8, with Roger Wilson moving to the bench.
Ireland international centre, Stuart Olding is selected among the substitutes and is in line to make his first appearance of the season if he is called upon.
Ulster beat the Ospreys at the Liberty stadium last year, but the Welsh region have won their last 10 home games and are one of two unbeaten sides in the RaboDirect PRO12 this season.
