**Conference A leaders Leinster return to action with a trip to the Dragons on Friday.** The Dubliners have not played a Guinness PRO14 fixture since their last trip to Wales – a 52-25 victory over the Scarlets on January 30. The Dragons were scheduled to host Edinburgh last weekend but saw the match postponed due to a frozen pitch and are still awaiting their first win since early December. Leinster have a four-point advantage over Ulster at the summit and will be looking to at least maintain that margin, with their rivals for top spot also in action on Friday at Glasgow Warriors. **The breakdown** As well as having not won at all since they triumphed over Glasgow on December 5, the Dragons have not registered a victory in Newport since their win against Zebre in early October.
