Leinster have suffered an injury blow before their Heineken Cup clash with Northampton with the news that Sean O'Brien has failed a fitness test.
O'Brien has not recovered from a 'dead leg', meaning Shane Jennings starts while Kevin McLaughlin comes onto the bench.
Meanwhile, the visitors have also made a late change with outside centre Dom Waldouck withdrawing.
George North moves to 13 as a result while Tom Collins comes in on the wing. Tom Stephenson is added the bench.
