Ulster are fast becoming a bogey team for the Ospreys who have suffered five defeats in six games against the province. Neil Doak's men are back in Wales this week, determined to bounce back from last Saturday's disappointing Champions Cup result in Llanelli.
Leinster and Connacht collide in a tasty pre-Christmas interprovincial cracker, with the hosts looking to avenge their defeat from earlier in the season and the westerners aiming to win in Dublin for the first time in 12 years.
Ulster head coach Neil Doak has made two changes to the team that lost narrowly to the Scarlets as the province return to GUINNESS PRO12 action away to the Ospreys on Saturday evening (kick-off 5.15pm).
Pat Lam has named his Connacht team to face Leinster at the RDS on Friday night in round 10 of the GUINNESS PRO12. Lock Aly Muldowney is the only survivor from the side that beat Bayonne 29-27 in France last weekend.
Munster have confirmed that backs Johnny Holland and Gerhard van den Heever are set for lengthy spells on the sidelines, while their Ireland international prop Dave Kilcoyne has been ruled out for a number of weeks.
Following their 29-27 away win in the European Challenge Cup, Connacht's Bayonne conquerors returned to Galway on Sunday night and joined the other members of the squad for training this morning as attention turns to the upcoming GUINNESS PRO12 derby clash with Leinster.
Munster lock Donncha O'Callaghan has been given a two-week suspension for an incident involving Ulster's Stuart Olding during last Friday's derby clash at Thomond Park. He will be suspended up to Sunday, December 14, meaning he will miss the Reds' back-to-back European games against Clermont Auvergne.
