**Leinster can climb to the top of Conference A on Saturday when they visit the Scarlets.** Victory over Conference B pace-setters Munster last weekend saw the Dubliners pull within a point of Ulster, and their trip to Llanelli will use up their game in hand over the leaders. The Scarlets have suffered back-to-back defeats to Cardiff Blues in their last two matches but could go second in Conference B with a win this weekend. Both sides will be impacted by Guinness Six Nations call-ups, with Leinster supplying 17 players to the Ireland squad and 11 Scarlets joining up with Wales.
