Newcastle Falcons continue to progress after announcing that Calum Green, Glen Young, Santiago Socino and Andrew Foster have all agreed to new contracts ahead of next season.
This news comes in the wake of the Kingston Park outfit's announcement that they have re-signed three exciting young players.
Second-rower Green, 25, has made 42 appearances since joining the club from Yorkshire Carnegie two years ago, the Norfolk native having come through Leicester Tigers’ academy.
"Calum has had a huge amount of game time since joining us and brings a lot to our forward pack. He has massive enthusiasm, gets through his work and is a valuable member of our senior squad." Director of rugby Dean Richards said in an official Newcastle Falcons press release.
The 21-year-old Young is a former Scotland U20, who has spent most of the season on loan to Doncaster Knights.
"Glen has benefited hugely from his year with Doncaster and we will look to integrate him more within our own squad next season," Richards said.
"He has matured a lot over the last 12 months and it is great news that we have been able to agree this new contract."
Socino, 24, is the younger brother of Falcons centre Juan Pablo Socino, the Argentina-born player that has converted from the back row to hooker.
"Santi is a real talent around the park who offers a lot of impact," Richards added.
"He is getting to grips with playing in the front-row and has gone well there for Darlington Mowden Park in National One this year, where he was recently named coaches’ player of the season.
"We look forward to his continued progression as a hooker and are glad to have him on board."
Foster, 22, completes the forward foursome, the North East native having stepped up from Blaydon.
The prop has already made three appearances including his recent Premiership debut against Saracens, having previously played against Brive and Enisei-STM in the Challenge Cup.
"Andrew has had to be patient in terms of his senior game time but has put in an incredible amount of hard work in training and at Blaydon," said Richards.
"His dual-registration has proved useful as he continues to develop, and he is one of many local lads around whom our squad is being built."
