Back rower Sam Graham has signed a new deal to remain with Premiership side Northampton Saints beyond this season.

Northampton director of rugby Phil Dowson says he has "been nothing but impressed" by Graham since first speaking to the player.

"His desire to grow and develop as a player has been second to none since then," Dowson told the club website.

"Sam does a lot of the unseen, ugly stuff out there on the field - the selfless stuff that goes a long way in rugby."
