Malcolm O’Kelly and Girvan Dempsey will make their 50th Heineken Cup appearances for Leinster when they face Gloucester on Saturday, KO 5.30pm.
Brian O’Driscoll captains the side and will again be partnered by Gordon D’Arcy at centre.
There are injury concerns for Leinster over Chris Whitaker (shoulder) and Cameron Jowitt (shoulder) who will both be given every chance to prove their fitness prior to kick off.
If Whitaker is again ruled out, Andrew Dunne – who earlier this week signed a contract until the end of the season – will take his place on the bench, with Willis starting.
Should Jowitt not make it, Stephen Keogh will make his Heineken Cup debut for the province with Adam Byrnes taking his place on the bench.
