In Guinness Pro-12 rugby, Munster and Leinster will name their teams around midday for tomorrow's meeting at the Aviva.
Hosts Leinster have won all 13 of the Pro-12 games they've played at the stadium, five of them against Munster.
It's been an evenly mixed start to the season so far for both Irish team; each side has won two and lost two games.
They're also evenly matched in their competitive history against each other; this will be their 39th meeting, and they've each won 18, and drawn twice.
Former Leinster, Connacht and Ireland hooker Bernard Jackman, who’s now coaching French Top-14 side Grenoble, joined us to discuss the game, and talk us through the injury news concerning Leinster's Sean O’Brien.
