Newcastle have continued their squad strengthening ahead of a possible Aviva Premiership return next season by signing Saracens flanker Andy Saull.
The England Saxons forward has agreed a two-year deal, the Falcons announced on their official website.
Saull, 24, will join former Saracens colleagues Adam Powell and Noah Cato at Kingston Park and he becomes their latest new recruit after Scotland international scrum-half Mike Blair and Harlequins fly-half Rory Clegg.
Saull has made more than 100 appearances for Saracens, while his Saxons debut came against Portugal in 2009.
"Andy is a fantastic signing who has the potential to achieve big things in the game," Newcastle rugby director Dean Richards said.
"He has benefited from an excellent rugby education with Saracens, coming through their academy and going on to play alongside a string of world-class players.
"I am thrilled that we have secured Andy's services."
Newcastle, who were relegated from the Premiership last season, currently top the Championship and are favourites to clinch promotion following next month's play-offs.
