Ciaran Frawley will start for Leinster against his future employers Connacht in the United Rugby Championship tomorrow.
He's been picked at full-back with Sam Prendergast at out-half for the reigning champions - who are captained by Dan Sheehan.
Dave Heffernan and Jack Carty are both out through injury for Connacht but Ireland internationals Bundee Aki, Cian Prendergast and Finlay Bealham all start for Stuart Lancaster's side.
Tonight Ulster welcome a much-changed Munster team to Belfast for an inter-pro derby, where the visitors can go top with a win.
