Gleeson returns for Leinster
Gleeson returns to the starting line-up for the Magners League derby and is one of four changes from the team that drew 16-16 with Ulster at Ravenhill last weekend.
Luke Fitzgerald starts on the left wing in a backline that includes Gordon D’Arcy, Shane Horgan, Girvan Dempsey and Brian O’Driscoll, who captains the side. Christian Warner partners Chris Whitaker at half-back.
