In the only other game last night, second from bottom Dragons beat second from top Ospreys 21-20 at Rodney Parade.
The visitors scored a 73rd minute try that Dan Biggar failed to convert and then the out-half saw his last gasp drop-goal come back off an upright.
That defeat for Ospreys means Leinster can widen the gap at the top of the table to at least nine points if they win in Cardiff later this evening.
