Squad News:Grand Slam winners Paddy Wallace, Rory Best and Tom Court have returned to the Ulster squad for the Magners League match against Leinster at the RDS on Sunday.Flanker Stephen Ferris has not been included after he dislocated his finger in the early stages of Ireland's historic win over Wales last Saturday.
The returning trio were on the replacements bench that day, though Best and Wallace played their part when coming in for Jerry Flannery and Luke Fitzgerald respectively.
Scottish wing Simon Danielli and Italian lock Carlo Del Fava also return to Matt Williams’s squad, as does number eight Robbie Diack, who has recovered from a fractured metatarsal sustained in the 21-15 defeat to Edinburgh in January.
Ulster trail second-placed Leinster by 11 points in the league but are coming off the back of a 2-0 win over Glasgow and the strengthened 25-man squad travels south, confident of another big scalp on its travels, having already beaten Munster 37-11 at Thomond Park.
Leinster coach Michael Cheika welcomed captain Leo Cullen and CJ van der Linde back to his side earlier in the week after both recovered from injuries.
Ireland centre Gordon D’Arcy, keen to get as much game time under his belt in the hope of a Lions call, was also included.
