'There is a great culture and hopefully I can help the team succeed while continuing my progression as a player, and I am sure that Franklin's Gardens will be a good environment for me in that regard.'

Northampton have also announced new contracts for props Tom Mercey and Alex Waller.

Saints rugby director Jim Mallinder added: 'All three players have plenty of experience, and because they are still in their early-to-mid 20s we believe that there is plenty more to come from them.

'I am that all three props have put pen to paper to be a part of the Saints squad going forward.'
