Johnny Sexton will win his 100th cap for Ireland after Andy Farrell named his team to play Japan on Saturday.
The Ireland skipper will be partnered by Leinster team-mate Jamison Gibson-Park, with regular scrum-half Conor Murray on the bench for the Autumn Nations Series game at the Aviva (1pm, live on RTÉ).
The Munster man has just made one appearance as a replacement since returning from the Lions tour.
With Robbie Henshaw still recovering from a foot injury, Bundee Aki and Garry Ringrose are the centre pairing, combining for the first time since the October 2020 Six Nations match against Italy.
Hugo Keenan continues at full-back for a 14th consecutive match with James Lowe and Andrew Conway on the wings.
𝐂𝐚𝐩𝐭𝐚𝐢𝐧. 𝐋𝐞𝐚𝐝𝐞𝐫. 𝐋𝐞𝐠𝐞𝐧𝐝. 𝐂𝐞𝐧𝐭𝐮𝐫𝐢𝐨𝐧.

Lions number 8 Jack Conan starts with Caelan Doris and Josh van der Flier at 6 and 7 making up an all-Leinster back row.
