Scotland winger Simon Danielli returns to the Ulster squad for Wednesday night's Magners League game against provincial rivals Munster at Ravenhill.
Danielli has been absent since injuring his ankle in Scotland's Six Nations game against Italy on 15 March.
Paddy Wallace, Rory Best and Stephen Ferris have all recovered from injury and take their places in Matt Williams' 26-man squad for the derby fixture.
Munster reached the Heineken Cup final by beating Saracens on Sunday.
Ulster are four points ahead of Connacht in the Magners League standings as both teams target a place in next season's Heineken Cup.
Meanwhile David Humphreys is not in the Ulster squad but may be fit to face Glasgow in Ulster's next game at Ravenhill on Saturday.
