Academy product centre Chris Harris has signed a new two-year deal with Newcastle Falcons in his breakthrough season at Kingston Park.
He marked his debut with a try against Bucharest in the European Challenge Cup in December, and since scored three in three Premiership games.
The Cumbrian, 24, had been on a dual registration deal with Rotherham.
"It's great news that Chris has chosen to commit for another two years," director of rugby Dean Richards said.
"Chris is a talented young man and exactly the type of player we are looking to keep hold of as we continue to build for the future of Newcastle Falcons."
Harris' Premiership opportunities have been carefully managed, with competition for places in the three-quarters alongside Juan Pablo Socino, Gonzalo Tiesi and Adam Powell.
"It doesn't mean I can relax because, if I want to be in the team, there are some pretty high quality players so I have to play and train well to get the shirt," he said.
"It does take a bit of pressure off knowing the future is sorted and I'm happy about it."
