Malcolm O'Kelly, a second half replacement for Nathan Hines last time out, starts alongside skipper Leo Cullen and Kevin McLaughlin continues his back row partnership with Sean O'Brien and Jamie Heaslip.
The province's back-line remains unchanged which means that there will be five full Ireland internationals on show behind the scrum, including Eoin Reddan who again partners Shaun Berne at half-back, and Brian O'Driscoll who starts at centre alongside Gordon D'Arcy.
The replacements bench will be confirmed closer to kick-off with a vacancy remaining over the second row position.
