There are no internationals this weekend, and so the Celtic League has a full programme. In Ireland it is an inter-pro weekend, as Munster travel to Belfast on Friday evening to take on Ulster, while on Sunday, Connacht will come to Donnybrook to meet Leinster.

Ulster are pretty much at full-strength for tonight's top-of-the-table clash, with just Andrew Trimble away due to international commitments. Munster are missing almost all of their pack, Anthony Foley being their only first-choice front-eight player at No 8. Just three points separate Munster and Ulster, so the result tonight will have a major bearing on how this season's contest unfolds.

Full squad details here.

The match is live on Setanta Sports, and kick-off is at 7.35pm
