Leicester Tigers have agreed new contract terms with Jono Kitto, George Catchpole and Jack Roberts beyond the end of the current season.
New Zealand-born Kitto moved to Welford Road earlier this season and, after making his debut against Wasps in November, he marked with first start with a try in the bonus-point win over London Irish on Sunday.
Tigers director of rugby Richard Cockerill said: "Jono is a young man who came here to challenge himself at a high level and he's settled in well. He is working hard on his game with Scott Hansen, Aaron Mauger and the rest of the coaching team.
"We have a good group of players at scrum-half and Jono will only get better as he develops alongside Ben Youngs, Sam Harrison and George Tresidder."
Kitto, 23, said: "I've enjoyed my time at the club this season and I was very keen to stay. It is a great club and it's a privilege to play here and a great environment to work in."
Catchpole joined the Tigers academy from school in Norfolk and won England age-group honours before making his senior debut in November 2013. He played a prominent part in the club's run to the LV= Cup semi-finals last season as well as gaining experience in the Aviva Premiership and European Champions Cup.
Director of rugby Cockerill said: "George is a good young player who has grown up within the Tigers environment. He established himself in the senior squad last season and with top-quality senior players around him, and Aaron Mauger and Geordan Murphy among the coaching team, we think he can continue to grow his game here."
Catchpole, 22, said: "I've been here a while now after coming into the academy and it's a great place to play your rugby. I enjoyed the experience when I got into the team last year and I want to keep working hard so I can make the most of those opportunities."
Roberts joined Tigers from Championship side Rotherham at the start of 2014/15 and played in the historic fixture against the Barbarians as well as in the run to the LV= Cup semi-finals in his first season.
Born in North Wales, Roberts played in the Welsh Premiership with Llandovery before reaching the Championship play-offs with Rotherham.
Cockerill said: "Jack has worked very hard since coming into the squad and he wants to challenge himself to be the best player he can be here. We have a very competitive backline and he has good people to learn from and develop with here."
Roberts, 24, said: "I've really enjoyed my time at the club and now I'm looking forward to staying and being able to take my opportunities when they come."
