Leinster host Ulster at the RDS on New Year’s Eve at 3pm as both teams look to gather momentum heading into the New Year. The Leinstermen are third after being toppled by Munster last week, while Ulster are on a high after three wins in four. Ulster are fourth in the table, five points and one place behind their hosts. What’s at stake? Leinster will be looking to close the gap on Munster and Ospreys at the top of the table. Leo Cullen’s side are on 37 points from 11 games just three points behind the Welsh outfit, who sit second, and five behind their Irish counterparts. Ulster, meanwhile, are on 32 points, but have a game in hand. They have a poor record at the RDS in recent years, and will be wary that a loss will open the door for Scarlets and Glasgow to leapfrog them in the table. Team news (Leinster Rugby): Coach Leo Cullen makes 12 changes to his starting line-up, but Ireland fly-half Jonathan Sexton has failed to recover from a hamstring injury. A completely new pack has been selected after their Boxing Day loss to Munster. Their all-international back row is a strong one, with Sean O’Brien, Josh van der Flier and Jamie Heaslip featuring. Team news (Ulster Rugby): Andrew Trimble returns to the Ulster line-up after coming back from a foot injury sustained on international duty on November. Les Kiss makes seven changes in all after Ulster’s 23-7 win over Connacht on December 23rd. Talking points: Both teams are missing key members of the squad, with Leinster missing international No.10s Jonathan Sexton and Joey Carbery. Ulster, meanwhile are without Ireland captain Rory Best. Fly-half duties fall onto youngster Ross Byrne, who has a seasoned operator as his opposite number in South African Ruan Pienaar – with Paddy Jackson unavailable for Ulster.
