“I’m enjoying playing in the Gallagher Premiership, it’s a new competition to me and something I’d always wanted to have a crack at.
“The lads have been great in terms of how they’ve welcomed me to the club, the set-up here is enjoyable and despite our current league position I’ve got absolute full confidence that we have the quality and mind-set to pull ourselves up the league.”
Newcastle Falcons director of rugby Dean Richards said: “I’m absolutely delighted that we have been able to agree a longer-term deal with John, having initially brought him here for the rest of the current season.
“He is a proven performer at the very highest level, he offers a lot to the side and his work around the breakdown and tackle area is absolutely top class.
“It’s great news that John sees his future with the Falcons, and it says a lot about the environment here that players of his quality are willing to sign.”
