The destiny of the Six Nations Championship will be decided in the next fortnight with Warren Gatland's unbeaten Wales heading to Murrayfield for a clash with an injury-hit Scotland before hosting Ireland in what Welsh supporters will be hoping is a tilt at a Grand Slam.
England, despite their loss in Cardiff, appear well equipped to gather up 10 points in their last two matches.
Joe Schmidt’s Irish side host France at the Aviva stadium hoping to rediscover a playing rhythm ahead of their assignment in Cardiff.
The Ireland Under-20 side are still fostering hopes of a Grand Slam and next up is a game against France as the reigning world champions visit Cork. If Ireland win then everything will be on the line in Colwyn Bay on the last weekend.
There are a couple of rounds in the Guinness Pro14 this month with several pivotal fixtures in terms of the playoffs beginning this weekend when Connacht host the Ospreys and Benetton welcome Edinburgh to the Stadio Comunale di Monigo.
At the end of the month, attention will turn to the Champions and Challenge Cups once again.
Leinster and Ulster meet in a quarter-final at the Aviva stadium, while Munster travel to Murrayfield to try and find a way past Edinburgh.
Connacht meet Sale for the third time this season in a Challenge Cup quarter-final at the AJ Bell stadium.
